Biological control of dengue epidemic in Sri Lanka
By Professor M. W. Amarasiri de silva
The dengue hotspot pattern observed in Sri Lanka in 2025 reflects several interconnected realities shaped by urbanisation, climate, and human mobility. Colombo continues to stand out as the country’s strongest hotspot. Its dense housing clusters, construction activity, and high daily movement of people create ideal conditions for Aedes aegypti to thrive. The combination of crowded neighbourhoods and rapid urban development ensures that even small pockets of stagnant water become breeding sites, allowing the mosquito population to regenerate quickly, despite control efforts.
Gampaha and Kalutara together formed a continuous coastalurban dengue belt. These districts share similar environmental and demographic characteristics—large suburban populations, expanding commercial zones, and frequent waterlogging during monsoons. Their proximity to Colombo also contributes to the spread of dengue, as human movement between districts facilitates the circulation of the virus. This coastal belt has become one of the most persistent dengue-affected regions in the country.
Kandy has shown elevated transmission, driven by hillside urbanisation and household waterstorage practices. As the city expands into hilly terrain, construction sites, terraced housing, and irregular drainage systems create numerous microhabitats for mosquito breeding. In many areas, residents rely on stored water due to intermittent supply, and these containers often become breeding grounds, if not properly covered. The combination of climate, geography, and human behaviour makes Kandy a recurring hotspot.
Kurunegala has emerged as a major inland hotspot with repeated outbreaks. Its role as a transportation hub, coupled with rapid suburban growth, has led to increased mosquito density. The district’s mix of urban and semiurban environments provides abundant breeding sites, and seasonal rainfall patterns further amplify transmission cycles. Kurunegala’s dengue burden has remained consistently high over the past decade.
Batticaloa and Trincomalee experienced rising case numbers, linked to rapid development and monsoon-driven breeding cycles. Both districts have seen significant expansion in housing, tourism, and infrastructure. Heavy monsoon rains frequently create standing water in lowlying coastal areas, while new construction sites add additional breeding opportunities. These conditions have contributed to a noticeable increase in dengue transmission in the eastern region.
Jaffna, meanwhile, faces periodic spikes, influenced by climate variability and urban expansion. The district’s unique climatic conditions, particularly rising temperatures and irregular rainfall, have made mosquito breeding more favourable in recent years. Urban growth, combined with waterstorage practices common in the peninsula, has created environments where dengue outbreaks can flare unexpectedly. These periodic spikes highlight how climate change and development patterns are reshaping dengue risk in northern Sri Lanka.
One Sri Lanka’s most persistent public health emergencies
Dengue fever has entrenched itself as one of Sri Lanka’s most persistent public-health emergencies, with the country recording more than 80,000 cases in 2023 and surpassing 60,000 cases by mid-2024, according to national surveillance data. In some years, the toll has climbed even higher, with 2017 marking a historic peak of over 186,000 cases, overwhelming hospitals and prompting emergency responses across multiple districts. Colombo, Gampaha, Kandy, Kurunegala, and Batticaloa have repeatedly emerged as hotspots, reflecting a pattern in which densely populated urban and semi-urban regions bear the brunt of transmission. The economic cost is equally staggering: dengue-related healthcare expenditure, lost productivity, and household financial strain collectively amount to billions of rupees annually. These figures underscore a reality that Sri Lanka has lived with for decades; dengue is not merely a seasonal illness, but a structural challenge woven into the country’s environment, infrastructure, and public-health landscape.
Resilience of Aedes aegypti mosquito
Despite extensive public-health campaigns, fogging operations, school-based awareness programmes, and community clean-up drives, dengue continues to return with alarming regularity. The Aedes aegypti mosquito, the primary vector of dengue, has adapted with remarkable efficiency to Sri Lanka’s climate and human behaviour. It thrives in warm, humid conditions, breeds in even the smallest containers of stagnant water, and has evolved to exploit the very environments humans create, construction sites, household water storage, discarded plastic, and clogged drains. Its eggs can survive for months in dry conditions, waiting for the slightest moisture to hatch. This biological resilience has made dengue control a formidable challenge, one that traditional methods alone have struggled to overcome.
Fogging, a widely used method in Sri Lanka, targets adult mosquitoes but has limited reach. It cannot penetrate every corner of a neighbourhood, nor can it eliminate eggs or larvae hidden in sheltered containers. Larviciding is more targeted but requires consistent application and community cooperation, both of which are difficult to sustain over long periods. Public-awareness campaigns, though essential, often face behavioural fatigue. People may clean their surroundings diligently for a few weeks, only for old habits to return once the immediate threat seems to have passed. The mosquito’s ability to exploit even small lapses in environmental cleanliness allows it to rebound quickly. As a result, Sri Lanka finds itself trapped in a cycle of control, decline, and resurgence that has persisted for years.
New possibilities
In recent years, however, scientific developments emerging internationally have introduced new possibilities for dengue control, particularly biological methods that intervene directly in the mosquito’s reproductive process. One such approach involves releasing specially bred male mosquitoes that carry a biological trait preventing their offspring from surviving. These males, which do not bite and, therefore, pose no risk to humans, are released into areas with high mosquito density. They mate with wild females, and the resulting larvae inherit the trait that causes them to die before reaching adulthood. Over time, this leads to a significant reduction in the mosquito population. Field trials in several countries have shown reductions of more than 80 percent in targeted areas, a level of suppression far greater than what traditional methods typically achieve.
Precision is the key
What makes this approach particularly compelling is its precision. It targets only the dengue-carrying mosquito species without affecting other insects or the broader ecosystem. Unlike chemical insecticides, which can harm beneficial species and contribute to environmental contamination, this biological method is species-specific and environmentally safe. It also leverages the mosquito’s own behaviour specifically, the male’s strong ability to locate females, to deliver the intervention effectively. The method does not rely on perfect community compliance or constant human vigilance. Even if some breeding sites remain, the released males continue to seek out females and disrupt the reproductive cycle. This makes the approach resilient in real-world conditions where complete environmental cleanliness is difficult to achieve.
Sri Lanka’s dengue situation aligns closely with the conditions under which this biological method has proven effective elsewhere. The country’s warm climate, high humidity, and dense urbanisation create ideal breeding conditions for Aedes aegypti. Urban areas, such as Colombo, Gampaha, and Kandy, experience repeated outbreaks, often linked to rapid development, inadequate waste management, and the proliferation of small water-holding containers. Semi-urban and rural areas are not spared either, especially where household water storage practices create opportunities for mosquito breeding. The mosquito’s adaptability means that even well-intentioned community efforts can fall short. A single forgotten bucket, a clogged drain, or a neglected construction site can become a breeding hotspot capable of sustaining transmission.
Strong foundation for biological methods
Sri Lanka’s public-health infrastructure, however, offers a strong foundation for integrating new biological methods into existing dengue-control strategies. The Epidemiology Unit, local Medical Officer of Health (MOH) offices, and Public Health Inspectors (PHIs) maintain detailed surveillance systems that track dengue cases and mosquito density. These systems allow authorities to identify high-risk zones and respond quickly during outbreaks.
The country has experience with biological control in agriculture and environmental management, meaning the concept of using biological methods to suppress pests is not unfamiliar. Sri Lankan scientists and institutions, including the Medical Research Institute and several universities, have the capacity to collaborate with international partners to evaluate and implement such approaches.
If Sri Lanka were to explore the biological suppression method, pilot projects could be conducted in selected high-density urban areas. These projects would involve releasing specially bred male mosquitoes over several months and monitoring changes in mosquito population density and dengue case numbers. The results would provide valuable data on the method’s effectiveness under Sri Lankan conditions. If successful, the approach could be expanded gradually to other districts. Importantly, this method would not replace traditional control measures but rather complement them. Community clean-up efforts, larviciding, and personal protection would remain essential components of dengue control. The biological method would strengthen the overall strategy by attacking the mosquito population at its root, reducing the number of mosquitoes capable of transmitting the virus.
The potential benefits for Sri Lanka are significant. A sustained reduction in mosquito populations would lead to fewer dengue cases, less pressure on hospitals, and reduced economic burden on families and the healthcare system.
Schools would face fewer disruptions, and communities would experience greater peace of mind during monsoon seasons. The environmental advantages are also noteworthy. Reducing reliance on chemical insecticides would help protect beneficial insects and reduce chemical exposure for humans. The biological method’s species-specific nature ensures that it does not interfere with ecological balance.
Sri Lanka’s dengue challenge is not merely a medical issue but a social and economic one. Families often face financial strain when a member falls ill, especially if hospitalisation is required. Parents worry about children during school outbreaks, and workplaces experience reduced productivity when employees are affected. The psychological burden is also considerable. Dengue outbreaks create anxiety, particularly when severe cases or fatalities occur in the community. A more effective and sustainable control method would alleviate these burdens and contribute to national well-being.
The country’s experience with COVID-19 demonstrated the importance of scientific innovation, public-health preparedness, and community cooperation. Sri Lanka mobilised resources, strengthened surveillance, and adopted new technologies to manage the pandemic. The same spirit of innovation and collaboration can be applied to dengue control. Biological suppression methods represent a new frontier in public health, offering tools that are more precise, sustainable, and effective than traditional approaches. By exploring these methods, Sri Lanka can position itself at the forefront of dengue-control innovation in South Asia.
Of course, any new method must be evaluated carefully. Public acceptance is crucial, and communities must be informed about the safety and purpose of releasing male mosquitoes. Transparent communication, community engagement, and scientific oversight would be essential components of any pilot project. Sri Lanka has a strong tradition of public-health education, and this can be leveraged to ensure that communities understand and support new approaches. The involvement of local scientists and institutions would also help build trust and ensure that the method is adapted appropriately to Sri Lankan conditions.
The fight against dengue requires both persistence and innovation. Traditional methods have served the country well but have not been able to eliminate the threat. The mosquito has proven too adaptable, too resilient, and too deeply embedded in the environment. To break the cycle of recurring outbreaks, Sri Lanka must consider new tools that go beyond conventional approaches. Biological suppression methods offer a promising path forward, one that aligns with scientific advances, environmental sustainability, and the practical realities of mosquito behaviour.
Sri Lanka stands at a crossroads in its dengue-control journey. The country can continue relying solely on traditional methods, accepting the recurring burden of outbreaks, or it can embrace new scientific approaches that offer the possibility of long-term suppression. The choice is not between old and new but between a limited toolkit and a more comprehensive strategy. By integrating biological methods into its dengue-control efforts, Sri Lanka can strengthen its ability to protect communities, reduce disease burden, and build a healthier future.
The challenge is significant, but so is the opportunity. Dengue has shaped Sri Lanka’s public-health landscape for decades, but it does not have to define the country’s future. With scientific innovation, community cooperation, and strategic planning, Sri Lanka can move toward a future where dengue is no longer a seasonal crisis but a manageable threat. The biological suppression method represents one of the most promising tools available today, and its relevance to Sri Lanka is clear. The time has come to explore it seriously, evaluate it rigorously, and consider how it can be integrated into the nation’s ongoing fight against dengue.
In moving toward this future, Sri Lanka would benefit from adopting a clear policy direction that recognises dengue as a long-term structural challenge requiring modern solutions. A national policy framework could begin with pilot deployments of biological suppression methods in selected high-risk districts, supported by rigorous scientific monitoring and community engagement. It could establish partnerships between local research institutions and international experts to ensure that the technology is adapted safely and effectively to Sri Lankan conditions. The policy could also strengthen environmental management systems, ensuring that waste disposal, urban planning, and water-storage practices reduce opportunities for mosquito breeding. Public-health education could be expanded to emphasise both traditional preventive measures and the role of new biological tools. Over time, the policy could evolve into a nationwide programme that integrates biological suppression with surveillance, environmental management, and community participation, creating a comprehensive and sustainable dengue-control strategy.
Such a policy would not only reduce dengue transmission but also demonstrate Sri Lanka’s commitment to scientific innovation and public-health leadership. It would signal a shift from reactive crisis management to proactive disease suppression, offering hope to communities that have endured the burden of dengue for far too long. The path forward requires courage, collaboration, and a willingness to embrace new ideas. But the reward, a healthier, safer, and more resilient Sri Lanka, is well worth the effort.
Integrating new developments into dengue control strategies offers a promising opportunity for Sri Lanka to enhance public health and protect communities across the island. By adopting innovative solutions, improving mosquito management, and building stronger public awareness, the country can significantly reduce infection rates and relieve pressure on healthcare facilities. I hope the government will pay attention to this new development in dengue control and take positive measures to address the issue, ensuring a safer and healthier future for everyone.
The following are some scientific papers explaining the new method for Sri Lankan scientists to follow. Research on Wolbachia-mediated biological control demonstrates that introgressing Wolbachia bacteria into Aedes aegypti populations significantly limits virus transmission and alters reproductive mechanisms (Al Noman et al., 2023).
Systematic reviews evaluating mathematical models of vector control highlight that biological methods, including the release of Wolbachia-infected mosquitoes, copepods, and larvivorous fish, offer self-sustaining mechanisms for reducing dengue transmission compared to traditional chemical alternatives (Ogunlade et al., 2023).
Broader vector-control frameworks integrate biological control alongside disease surveillance and biotechnological innovations as essential components of a multi-pronged approach to dengue mitigation (Procopio et al., 2024).
Also, there are number of TED talks on the subject such as TED talk on biological control of dengue fever. You may google and find these valuable discussions which explains the method

UN at Crossroads, Trump nearing End of the Road
by Rajan Philips
Down but not out may be too uncharitable a way to describe a global agency that was launched with lofty expectations 81 years ago, and has just entered its ninth decade of existence with more forebodings than promises. The precarity of the UN’s circumstance is also a reflection of the crassness of its chief benefactor, the United States of America under its current president. Stellar American Presidents Franklin Roosevelt and Harry Truman, both Democrats, led their country to virtually bankroll the formation of the UN after World War II. President Truman handpicked his predecessor Franklin Roosevelt’s widow and turn-of-the-century President Theodore Roosevelt’s niece, the highly accomplished Eleanor Roosevelt, to spearhead the drafting of the UN Charter of Rights. That was the beginning of the era of human rights in human history. That was also the early stirrings of the civil rights era in American history.
From the plenitude it projected in 1945, America has fallen to the pits under its current President Donald J. Trump. The sight of his arriving at the UN with Melania Trump as First Lady, who may know little or nothing about Eleanor Roosevelt, the greatest First Lady that America has had, says all about everything that is wrong with the US and its fallout for the UN. After Americans elected Trump to a second term as President, the fear of Trump pulling the US out of UN always loomed large. More so, in the wake of Trump-ordered withdrawals from UN agencies and the ungenerous defunding of US Aid programs. Last year at its 80th anniversary, UN insiders were wondering whether the agency had the wherewithal to keep going. In January this year, there were fears of an “imminent financial collapse.”
But nothing untoward happened. Trump did not pull US of the UN. Instead, the Trump Administration gave a financial breather by making a part payment of $725M out of a total $2.0 billion outstanding US dues to the UN. A further $102M was added to support UN peacekeeping. The payments were made a week before the Annual Sessions, perhaps as the US President’s voluntary entrance fee to address the General Assembly. The truth of the matter is that Trump needs the UN forum to validate himself, at least to his base in his own country.
His own actions overseas throughout 2026 – in Venezuela, in Iran and the Middle East, and on Greenland, not to mention his global tariff war or his bully-thy-neighbor bearing towards Canada – have forced him to show up and make his case at the UN, to his own satisfaction. The assembly hall was virtually full for his speech but it persuaded no one except his own entourage and the delegates from Israel. The same could be said of Israeli Prime Minister Benjamin Netanyahu, who braved the ICC (International Criminal Court) arrest warrant against him to show up at the UN. Unlike during Trump’s speech, UN delegates left the hall in droves as Netanyahu arrived at the podium.
Besides the two notorious attendees, there were powerful absences this year, including China, India and South Africa, the heavyweights of the Global South and three of the five founding members of BRICS (Brazil, Russia, India, China and South Africa). But none of them would wish the withering away of the UN, the way Trump and Netanyahu may entertain thoughts about a world without the UN. Even so, Trump has not precipitously pulled the US out of the UN in the first two years of his second term, and he does not have much time left to do any serious damage to the agency in the future.
Not only time, but also power is running out of Trump’s executive grasp. All indications are that Trump and the Republican Party will likely lose control of both the House and the Senate in the November midterm elections that are barely 20 days away. Even if Democrats do not win control of the bicameral Congress, the Trump Administration is already in disarray, and his Maga base is cracking up with infighting among wannabe Trumps.
What seems to be hitting home almost all Americans is the extent of first family corruption that has been growing exponentially during Trump’s second term as president. Trump’s personal fortunes have allegedly expanded by $2.2 billion in 2025. It is this barefaced moneymaking from the White House that is angering American citizens and raising expectations of a landslide electoral rebuke in November.
UN’s Predicaments
Even though Trump’s powers are waning and his threats are receding, the UN’s own circumstances are not getting any better. Its challenges involve both global turmoils that the agency has to deal with, as well as organizational weaknesses that impair its effectiveness and its influence over member countries. “Restoring Trust, Managing Transformations: A United Nations That Delivers for All,” is the agency’s official theme for its 81st year. The theme is more organizational than achievement oriented. On the eve of the 81st Anniversary, the US Statement Department declared on its website a goal of its own for the UN: “at this year’s session, the United States is pursuing one clear goal: delivering prosperity through peace, by bringing the UN “back to basics.”
Back to basics, whatever that might mean, has long been an American refrain for the UN. Under Trump and Secretary (of State) Marco Rubio, it has taken the form of an ideological fight against the so called global left elitists. The General Assembly sessions this year grappled with a range of issues, including climate change, AI threats, the Russia-Ukraine war and the US-Iran war, the tragedy of Gaza, and the elusive two-state solution for Israel and Palestinians.
The climate change and AI crises are manifestly 21st century addons, all the others are new manifestations of old problems – as old as the UN itself. What is remarkable is that Trump has placed his villainous stamp on every one of these issues, and has contributed nothing to positively resolving any of them. When the principal superpower goes rogue there is little that a global agency like the UN can do to contain the fallout.
Yet the world cannot be without an organization like the UN. Almost all countries and their leaders would like the UN to continue even if only a few of them would be inclined to abide by its decisions. In fact, the world needs a stronger UN and not a weak UN. That was the message of the departing Secretary General António Guterres in what was his last speech to the General Assembly. “The world does not need a weaker United Nations,” said Secretary Guterres, “it needs a U.N. strong enough to face the world as it is — and determined enough to build the world as it should be.”
Mr. Guterres will be leaving the UN on December 31, 2026 after completing two five-year full terms in office. The search for a new Secretary General to succeed Mr. Guterres has begun but early signs are that there is no immediate consensus candidate to succeed him. The UN Secretary General (UNSG) is the de facto head of the organization, and is appointed for a term of five years by the General Assembly on the recommendation of the Security Council. The five permanent members of the Security Council can exercise their veto on a candidate, while no citizen of theirs can be a candidate for the position.
The eventual appointee has always been a compromise candidate from on of the ‘middle powers’ or smaller countries. In general, candidates who are first appointed with grudging unanimity often get their second term approved with generous unanimity. While there is no term limit on a Secretary’s tenure, incumbents have avoided going beyond two terms since the 1981 vetoing by China, of the third term bid by Austria’s Kurt Waldheim. And the only Secretary General to be denied a second term was Egypt’s Boutros Boutros-Ghali thanks to American vetoing in 1996.
Finding a Secretary General
Since 1997, the SG appointments have been following a rotational system to give representation to the UN’s five regional groups: African Group, Asia-Pacific Group, Eastern European Group, Latin American and Caribbean Group, and Western European and Others Group. Although the principle of gender equality is acknowledged, so far no woman has been appointed as Secretary General. It has been a long wait, considering the role played by a woman, Eleanor Roosevelt, in the setting up of the UN charter enshrining gender rights, among others.
Secretary General António Guterres is the ninth Secretary General that UN has had since its inception 1945. He is the fifth UNSG from a European country – after Britain’s Gladwyn Jebb who started the list; Trygve Lie of Norway; the illustrious Dag Hammarskjold of Sweden whom President Kennedy called “the greatest statesman of our century,” after his plane crash death in Rhodesia (now Zambia), in 1961, which was also attributed to the CIA by global rumour; and Austria’s Kurt Waldheim.
Hammarskjold was succeeded by Burma’s U Thant who became the first non-European and first Asian Secretary General. Waldheim succeeded U Thant, and after Waldheim it was Latin America’s turn with the appointment of Javier Perez de Cuellar in 1982. Cuellar was followed by Egypt’s Boutros Boutros-Ghali, whose successor was Ghana’s Koffi Annan, the first UN insider to become the Secretary General. After Koffi Annan it was South Korea’s Foreign Minister Ban Ki-moon. António Guterres, who succeeded Ban Ki-moon, had been Prime Minister of Portugal (1995-2002) and is the first head of government to become UN Secretary General.
António Guterres’s main legacy may well be that he was the world’s most persistent voice on climate change. In an interview he gave Fiona Harvey, Environment Editor of the Guardian (September 22), he said as much while admitting that ‘voice’ is all that a UN Secretary General can muster as the office “has not much power, and there is no money.” He went on, “it is my duty to use that voice without any compromise, to tell the truth and to alert the international community to the dangers it faces. I have not the power to all of a sudden make everybody invest in renewables, but I have the duty to tell people that unless we accelerate from fossil fuels to renewables, unless we drastically reduce emissions in the next decade, we will be facing dramatic problems that will impact on the whole of humankind.”
An Electrical Engineer by profession and a former leader of both the Socialist Party of Portugal and the Socialist International, Guterres has no qualms about calling regressive spades for what they are: “There are vested interests that are interested in maintaining the present development model based on fossil fuels. You have a systematic campaign that is strongly financed by the huge profits of the sector that tries to divert attention [from] the impacts of fossil fuels.”
Although he has not been able to achieve much, Mr. Guterres’s legacy on climate actions will be a hard act to follow for his successor. Going by UN’s rotational system, this time it is the turn for someone from Latin America or the Caribbean to be appointed as Secretary General. The prospect of a fellow head of government, former Chilean president and UNHRC High Commissioner Michelle Bachelet, succeeding Guterres has been blown out of the water by US veto threat.
That leaves seven candidates contending with varying levels of support and veto threats in the Security Council. Four of them are women: Rebeca Grynspan, 70 year old Economist, former Vice President of Costa Rica, and current head of the U.N. Conference on Trade and Development; Ms. Rodrigues-Birkett, 53, Guyana’s former Foreign Minister and UN Ambassador since 2020; María Fernanda Espinosa, 62, former Foreign Minister and Defense Minister of Ecuador, as well as UN Ambassador; and Ivonne Baki, 75, another Ecuadorean politician and diplomat, as well as the country’s first female ambassador to the United States, to France and Qatar.
The three male candidates are: Olara Otunnu, 75, an Ugandan politician and diplomat, and a former UN under secretary general to Kofi Annan; Rafael Grossi, 65, Argentinian career diplomat and head of the International Atomic Energy Agency, who has played a prominent role in the monitoring of Iran’s nuclear program and nuclear spill threats in Ukraine after Russian invasion; and Macky Sall, 64, a Senegal President and Prime Minister.
There is no clear front runner, but Costa Rica’s Rebeca Grynspan and Guyana’s Rodrigues-Birkett would seem to be garnering the most support in the Security Council. At long last, UN may have a female Secretary General. But the political world is more likely transfixed with the November midterm elections in the US and their fallout for the Trump presidency, than being concerned about the next UN Secretary General. Any fallout for the Trump presidency will have implications for the world and the United Nations. The implications will not amount to a swift reversal of all the follies of Trump and return to pre-Trumpian normalcy. Rather they would slow down and avoid further dismantling of the world order and its agencies which did not seem possible even as recent as a year ago.

When Spies Go Rogue
by Nilantha Ilangamuwa
A former German intelligence chief has been arrested on suspicion of treasonous espionage just as a former senior CIA official has pleaded guilty after using his government position to defraud the United States of approximately $194 million, including the acquisition of 298 gold bars, both reported last week. David J. Rush fabricated highly classified government programmes to create the appearance of legitimate authority and divert public money into property, gold and luxury assets. US prosecutors also say he admitted giving a foreign government official information identifying a secret American intelligence source.
August Hanning, Germany’s former BND chief, faces a very different set of allegations. German prosecutors accuse him of obtaining classified BND information through a former subordinate who remained inside the agency and of using some of that material in dealings involving foreign intelligence. Hanning denies wrongdoing and hasa not been convicted. The cases differ. One concerns a guilty plea to fraud, the other an espionage investigation. Their near-simultaneous appearance exposes a vulnerability in modern intelligence services. Secret institutions depend on trust, yet that trust creates opportunities for abuse from within, especially when privileged knowledge survives a person’s relationship with the state.
The Bundesnachrichtendienst (BND) is being prepared for a more active role as Germany faces Russian espionage, cyber operations, sabotage and other forms of hybrid pressure. The proposed legislation would expand its ability to interfere with foreign computer systems and conduct disruptive operations. Peter Neumann, the security scholar interviewed by Die Zeit, sees the change as overdue. Germany, he argues, cannot expect French, British and Dutch services to possess capabilities that Germany itself restricts while relying heavily on allied intelligence, particularly from the United States. Former Justice Ministry official Peter Schantz accepts that German capabilities need strengthening but questions whether wider powers provide the answer. His concern centres on sabotage, cyber countermeasures, escalation and political responsibility. The disagreement is about the boundary between intelligence collection and state action.
A failed intelligence operation can produce bad information. A failed sabotage operation can produce casualties, retaliation and an international crisis. Schantz has questioned whether the Independent Control Council, despite its legal review function, provides sufficient political accountability for sensitive operations. Neumann, by contrast, argues that excessive legal and procedural restrictions have made German intelligence slower and less effective than comparable European services. The more consequential an operation becomes, the harder it is to separate legality, secrecy and political responsibility. It concerns the institutional consequences of moving an intelligence service from observing foreign activity towards intervening directly in it. Once the BND possesses capabilities designed to disrupt foreign systems, questions about authorization, review and responsibility become inseparable from the operational purpose of those capabilities.
The Hanning investigation gives this debate a serious internal dimension. Prosecutors allege that Hanning, who led the BND from 1998 to 2005, later obtained roughly 2,000 documents from Manfred D., a former office manager who remained inside the agency and worked for Hanning’s successors until 2026. Investigators allege that some documents came from sensitive BND reporting and could have contained information originating with partner services. The concern is the alleged channel through which it was obtained. A former chief did not allegedly need to penetrate the agency from outside. Prosecutors say a trusted former colleague remained an information link into an organization whose value depends on controlling access. Hanning’s arrest is not proof of guilt, but the allegations raise questions about how effectively the BND detects misuse of privileged relationships.
History provides several reminders. Aldrich Ames betrayed the CIA to the Soviet Union, Robert Hanssen spied for Moscow from inside the FBI, Kim Philby reached senior British intelligence positions while secretly working for the Soviets, and Günter Guillaume penetrated West Germany’s political centre for East German intelligence. These cases are not equivalents of Hanning’s allegations. Their relevance is narrower. Intelligence organizations are unusually exposed to insiders because sensitive information is concentrated in trusted individuals. Hanning’s case, if the allegations are established, would add a different dimension because the alleged access occurred after he had left the BND. The question then extends beyond the classic insider threat to the relationship between intelligence agencies and their former senior personnel.
Senior intelligence officers leave office with knowledge, contacts and reputations built through decades of public service. Moving into consultancy or corporate work is not inherently improper. Yet the boundary between expertise and privileged access can become difficult to police when former officials continue dealing with people connected to foreign governments, security businesses or sensitive disputes. A former intelligence chief can enter a boardroom carrying decades of public investment in his expertise. The issue is whether classified information, institutional relationships or official prestige can become private assets. That concern is particularly relevant when a former official’s commercial value is closely connected to the networks developed while holding public authority. The difficulty lies in the point where legitimate professional experience becomes access to information or relationships that were created for public purposes.
The Rush case shows another side of the same vulnerability. According to US prosecutors, he created fictitious classified programmes and used the authority surrounding them to make fraudulent transactions appear legitimate. The result was a diversion of public money into private wealth. His case is not an espionage equivalent to Hanning’s, but it demonstrates how secrecy and official authority can obstruct ordinary scrutiny. The fewer people authorized to know what a programme is, the more important internal controls become. Secrecy protects intelligence work, but without effective controls it can also shield misconduct.
Germany faces a more difficult security environment. Neumann’s concern about dependence on allied intelligence is legitimate, particularly when Germany expects partners to share sensitive information while its own service has more limited powers. Capability also creates a security burden. An agency authorized to conduct offensive cyber operations will possess more access, more technical capacity and more sensitive information. The question is whether safeguards are equally strong. If partner services believe sensitive material can move from the BND into private networks, cooperation becomes more difficult.
The treatment of former intelligence officers belongs here. Retirement can create a combination of vulnerability and influence. Former officers may lose institutional protection while retaining knowledge valuable to private interests. Professional reputation can become a commercial asset, while accusations can destroy reputations before a court establishes the facts. Hanning remains legally entitled to the presumption of innocence. If the allegations collapse, reputational consequences remain; if proved, the case raises questions about internal controls. The affair demonstrates that retirement is not a clean break from senior intelligence responsibilities. Former officials remain part of the institutional history of the services they once led, and their subsequent activities can affect perceptions of those institutions even when no criminal conduct is established.
Germany’s problem is not unique. Every nation-state faces the dilemma of maintaining capable intelligence services while protecting people who may carry their secrets, networks and responsibilities long after formal service has ended. Greater operational capability also increases the importance of authorization, oversight, internal security and post-service restrictions. If classified material moves into private networks, confidence between intelligence services becomes harder to maintain.
The arrest of Hanning and the Rush guilty plea arrive at a significant moment for modern espionage. Neither case proves that intelligence agencies are inherently corrupt, and the two men face different legal circumstances. Their significance lies in a common institutional problem. Intelligence services concentrate information, authority and trust in a small number of people. That concentration is necessary, but it also creates opportunities for abuse, insider compromise and conflicts of interest.

30 Eggs, Bawa’s Breudher Pan and a Culinary Who Did It?
From The Pathfinder Collection

Let There Be Light
At Lunuganga, Geoffrey Bawa’s country home, a stone bishop stands along the passage from the entrance vestibule, crozier in hand and apparently illuminated from nowhere. Look up and the source reveals itself: a small angled shade, painted white and cut precisely to throw its beam down onto the figure. Channa Daswatte, Bawa’s protégé, told me that it was, in fact, fashioned from a sardine tin—a juxtaposition with the saintly figure that makes the joke all the more irreverent.
Bawa was also an avid collector of beautiful and unusual objects, and among those at Number 11 sits a well-weathered old breudher pan. Its dark, pitted lid contrasts with the worn coppery tones of its spiral-fluted body. The heavy, broad lid, the elegant fluted body perched on long, slender legs, and the small protuberance at the centre of the lid give it an unusual and distinctive appearance, whose logic becomes clearer when the lid is lifted to reveal the tall central column beneath.

In Pettah, the old quarter of the city, the Dutch Period Museum holds another breudher pan, dating to about 1750–1800. Labelled simply as a “cake mould”, it is identified by Lodewijk Wagenaar in Cinnamon & Elephants as a broeder pot made of copper and tin. It follows the same essential logic as the Bawa vessel: a deep, fluted pan with a tall central column projecting above the rim and three sturdy legs. Unlike the Bawa pan, two prominent curved handles rise from either side and its rectangular legs are much heavier. Seen from above, its broad scalloped rim forms a distinctive petalled outline.
Though the museum vessel survives without a lid, its broad upper flange could have accommodated one. If so, the arrangement would have differed from the Bawa pan: the upturned handles would have prevented a cover from fitting down over the outer lip in the same way. They may have helped steady one from either side. The details differ, but the essential features remain the same.
The provenance of these two vessels remains uncertain. Wagenaar does not mention where the Dutch Period Museum pan was made, although he notes that broederpannen occur repeatedly in eighteenth-century Ceylonese inventories and auction records. His research also shows how easily objects travelled through the Dutch maritime world: goods moved between Holland, Batavia, Ceylon and the VOC settlements of coastal India, while European and Eurasian households acquired characteristically Dutch utensils locally at auction. Their presence in Sri Lanka tells us where they were used and valued, but not necessarily where they were made.

Built for the Hearth
The two pans reveal how breudher was once baked in Sri Lanka: they were designed for the hearth rather than the oven. The Bawa pan makes the engineering especially clear. Its thick metal walls enclosed the dough, while the long legs held the vessel above the embers and the heavy, close-fitting lid could carry hot coals, providing heat from above. Most ingenious was the hollow central column. It reduced the mass of dough through which heat had to travel while acting as a chimney, allowing rising heat to pass through the centre of the bread and out through the lid. The fluting increased the surface exposed to the heated metal while giving the finished bread its tall architecture. Together, these features distributed heat around, above and through the dough—in effect creating a miniature, self-contained oven within the hearth.
A traditional broeder mould from North Holland, made in Germany around 1880, offers a striking comparison. Shallower and made of earthenware, it shares with the Bawa pan a lid, central column and slanted fluting. German earthenware circulated widely in the Netherlands, so its place of manufacture need not imply a specifically German origin for the form.
Jacco Spil, General Director of the bakery museum in Medemblik, North Holland, explains that a domestic broeder could be cooked either in a special cloth bag or in a lidded mould. Other Dutch museum examples show that such broeders were traditionally boiled or steamed rather than baked directly over the hearth. The same general shape could also be used for tulband, a different, cake-like preparation baked in the oven.

The surviving Dutch moulds provide an illuminating contrast with the Bawa pan. They have the familiar central tube and fluted ring shape, but the examples examined here have no integral legs. The Bawa pan incorporates the requirements of hearth baking into the vessel itself: long legs hold it above the embers, the heavy lid can carry hot coals while enclosing the dough, and the central tube projects through the lid to channel heat through the centre. It is this integration of functions, above all the projecting chimney, that sets the Bawa pan apart.

As the hearth gradually gave way to the oven in Sri Lanka, the breudher pan dispensed with its legs and heavy lid, while the projecting chimney became unnecessary. The central tube was shortened to just below the rim, retaining its role in reducing the thick central mass of dough but no longer functioning as a chimney. The oven had taken over much of the work the old pan once had to perform for itself.
From Broeder to Breudher
English speakers might assume that the Dutch broeder means “bread”, especially since brood is the Dutch word for bread. But broeder means “brother” and can also refer to a member of a religious order. A nineteenth-century Dutch dictionary suggests that the food acquired its name because its rotund, plump shape recalled a stout monastery brother.
Rather than a single fixed preparation, broeder belonged to a broad, regionally variable family. Pagrach-Chandra records versions fried in a heavy pan, steamed in a covered mould as ketelkoek, or boiled in a cloth as Jan in de zak. The names broeder, boffert and Jan in de zak could also overlap in local usage. Such preparations are well represented in eighteenth-century cookery books.
In Ceylon, the Dutch spelling broeder persisted through Dutch rule and well into the British period. Breudher is the modern conventional Sri Lankan English spelling, while in Sinhala the bread has been known as burudala.
Deloraine Brohier places breudher’s origins in “Holland and the Hanseatic Towns of the low-country, and elsewhere in Flanders”. Wagenaar traces the name more specifically to West Friesland in North Holland, home of the VOC chambers at Hoorn and Enkhuizen.
Spil distinguishes between broeders made at home and those produced by professional bakers in West Friesland. The domestic version used a yeast dough, sometimes with currants. The bakery broeder, by contrast, was a baked round loaf containing currants or raisins, with a cinnamon-and-sugar filling at the centre. The Hoornse Broeder belongs to this baked tradition.
In parts of Friesland, boffert could also refer to a yeasted celebration cake baked in a tulband pan. Here the relationship to Sri Lankan breudher becomes closer still: an enriched, yeasted festive bread or cake shaped in a tall ring.

Beyond the Netherlands, comparable traditions existed in German-speaking Europe. The Dutch tulband and German Gugelhupf belonged to the same broad family of ring-shaped breads and cakes. Maria Riesin’s 1755 cookbook from Franconia, in southern Germany, contains sixteen Gugelhupf recipes, thirteen of them yeast-leavened. The Fränkisches Freilandmuseum, a museum in Franconia that has studied the manuscript, notes that one recipe calls for twenty eggs to a pound of flour—a ratio it describes as high but not unusual—while a “simple” Nuremberg version of 1733 used six yolks.
Thirty Eggs
Deloraine Brohier, in A Taste of Sugar and Spice, records a broeder recipe from what she calls the “Brohier Manuscript”, a slim, yellowed typescript titled Rare Recipes of a Huisvrouw of 1770, found in her father R. L. Brohier’s collection. It calls for only five components:
3 lbs wheaten dough
1 lb butter
1 lb sugar
¼ lb raisins
30 eggs

The recipe is scaled for a large batch, but its proportions are what stand out. One pound of sugar to three pounds of prepared dough is generous for a bread; thirty eggs are startling. Brohier makes clear that only the yolks were used, but even so, the quantity is remarkable.
The curious phrase wheaten dough specifies the flour type, a distinction that may have mattered in a local kitchen where rice and other familiar flours were more common than imported wheat. Yet the recipe says nothing about how the initial dough was made or what leavened it. A 1925 contribution to the Journal of the Dutch Burgher Union, appearing under the heading “Household Hints” as “How to make Broeder”, came from an unnamed female member described as “a much valued lady correspondent”. She notes that dough “can be purchased at any bakery” and would arrive “highly leavened”. The leavening agent used by eighteenth-century bakers may remain unknown, but plain bread dough clearly formed the starting point for breudher.
Breudher-making therefore begins where ordinary bread-making ends: with an already fermented wheat dough transformed through the laborious incorporation of butter, sugar and an exceptional quantity of egg yolks.
From there, Brohier’s instructions are quite clear. The dough is kneaded firm, then butter in pats is gradually worked in. The yolks follow one by one, each thoroughly incorporated before the next is added, and finally the sugar. Kneading continues throughout, alternating with beating or “clapping”; Brohier stresses that this gradual incorporation is necessary to keep the batter firm. The mixture is then placed in the pan and, if possible, left in the sun for half an hour to help it “bake lighter” before going into a “hot oven”. In modern baking terms, gradual enrichment helps such a rich dough retain its structure.
Elsewhere in the book, recalling Christmas in her grandmother’s household, Brohier remembers breudher-making as a whole morning’s work, with her grandmother and aunts “slapping and turning, spooning and twisting” the mixture by hand. Her recollection supplies the time and physical effort compressed by the recipe.
The same correspondent offers a series of practical hints for judging the mixture. If it began to “run”, she advised stopping the addition of yolks because the sugar still had to go in. Incorporating all thirty had been regarded by an earlier generation as “a triumph of culinary art”. She wonders whether success depended on what she calls “the excellency of the dough” supplied to the cook, or simply on the smaller size of village eggs; the reason, she says, “was not clearly known”. In practical baking terms, both could matter: how much yolk the dough could absorb would depend on its condition and fermentation, while larger eggs would contribute more yolk by weight.
Before the raisins were added, the mixture was worked until hollow bubbles appeared, which the writer took as proof that it had been successfully aerated. The desired result was “light and spongy”.
The basic formula proved remarkably durable. The Ceylon Daily News Cookery Book, first published in 1929, still calls for two pounds of dough and twenty yolks, almost exactly preserving the older proportion. Chandra Dissanayake records a three-pound, thirty-yolk version alongside later adaptations using fewer eggs, while Charmaine Solomon simplifies and broadens the formula further. Across the twentieth century, breudher remained recognizable even as cooks adapted it for economy, convenience and changing kitchen practice.
When Recipes Travel
The recipes diverge most clearly in their enrichment. Many domestic Dutch broeders contained little or no sugar in the dough and were sweetened only when served, while the Hoorn and Frisian baked versions were richer. In Sri Lankan breudher, sugar, butter and an unusually large quantity of egg yolks were worked directly into the fermented dough.
Eighteenth-century German Gugelhupf recipes show that yeasted breads or cakes could contain substantial quantities of eggs and fat. Sugar appears more sparingly in these older German recipes and remained expensive. Against that background, the pound of sugar worked into three pounds of prepared dough is notable—and may point elsewhere.
Brohier draws attention to the Portuguese taste for sugar and to the ways Portuguese and Luso-Eurasian foodways entered Dutch-Ceylonese households. Iberian confectionery—particularly the convent traditions of Spain and Portugal—also made conspicuous use of sugar and egg yolks. Together, these parallels make Portuguese influence plausible, perhaps less in breudher’s basic structure than in the degree of richness it acquired in Ceylon.
Many European men serving the VOC married Portuguese-Eurasian women in Sri Lanka and elsewhere in Asia, while cooks and others in colonial households often came from communities shaped by earlier Portuguese influence. Such households offered precisely the setting in which northern European baking traditions and Luso-Eurasian tastes might meet.
It is tempting to imagine that a well-loved festive bread—and perhaps even the specialized vessel used to bake it—travelled with people on VOC voyages, carrying something of home across oceans into unfamiliar places. In new kitchens it acquired new ingredients, techniques and meanings, becoming something more than the dish that had first set out.
