The Diego Garcia treaty, signed by the UK on 22 May 2025, secures the future of the strategically critical UK-US military base on Diego Garcia. This base is vital for UK defence and intelligence capabilities, and the safety and security of the British people.
The Government also worked to ensure that the treaty includes important provisions for Chagossians, including the establishment of a trust fund to benefit the community and a route to resettle the islands of the Chagos archipelago other than Diego Garcia. These and other related Chagossian issues have been the subject of significant debate in both Houses. The Government are pleased to update the House on recent developments.
Chagossian Trust Fund
Under the terms of the treaty, the UK will capitalise a £40 million trust fund for the benefit of Chagossians, which will be established by Mauritius. On 12 December, the Mauritian Government approved introduction of primary legislation to establish the trust fund. The Bill will be published on the website of the Mauritian Parliament and can be viewed on the Government Information Service portal of the Government of Mauritius https://gis.govmu.org It confirms the principle that the trust fund will be operated for Chagossians, by Chagossians.
Decisions on the use of funds will be taken by a trust fund management board. The board will comprise 12 members, seven of whom will be Chagossian, ensuring majority representation. The chair of the trust fund will be a Chagossian, selected by the Chagossian members of the board. Following extensive representations and engagement by this Government, the Bill also now confirms that a UK-based Chagossian representative will sit on the board alongside representatives living in Mauritius and the Seychelles. The UK High Commissioner to Mauritius will also attend board meetings.
We welcome these commitments by Mauritius which will ensure the trust fund reflects the full spectrum of perspectives within the Chagossian community.
Eligibility to Participate in a Programme of Resettlement
The treaty enables Mauritius to develop a programme of resettlement on islands other than Diego Garcia. This agreement is the only viable path to resettlement on the archipelago. The UK Government have been in talks with Mauritius to ensure that this programme is open to all Chagossians, irrespective of their country of residence. The Mauritian Government confirmed on 12 December that eligibility to resettle will apply to Chagossians born on the archipelago before 31 December 1973, and children of parents either of whom were born on the archipelago before that date.
UK-based Chagossians who do not hold Mauritian citizenship and meet these criteria will be eligible for Mauritian citizenship, and therefore able to participate in any future programme of resettlement. All Chagossians will remain eligible for British citizenship under the current citizenship pathway. Chagossians will be able to hold both British and Mauritian citizenship.
My noble Friend the Minister of State for International Development and Africa, the right hon. Baroness Chapman of Darlington, has made the following statement:
On 12 December 2025, the UK announced a package of four sanctions designations under the Sudan (Sanctions) (EU Exit) Regulations 2020—the Sudan regulations. These sanctions respond to the appalling atrocities committed by the Rapid Support Forces in and around El Fasher, north Darfur, which the RSF captured on 26 October 2025. There is overwhelming evidence of mass killings of civilians; ethnically targeted executions; sexual violence, including gang rape; abductions for ransom; widespread arbitrary detention; and attacks on health facilities, medical staff and humanitarian workers. This scale of suffering is unimaginable, with women and children bearing the heaviest burden in what is now the largest humanitarian crisis of the 21st century.
Since the start of the war, the UK has worked ceaselessly to bring an end to the fighting, alleviate the suffering and protect civilians. The UK remains the third largest bilateral donor to Sudan. The Prime Minister has committed to protecting UK funding to support people affected by the crisis, a clear signal of our unwavering commitment to justice for the Sudanese people.
Accountability for crimes remains at the heart of our response. That is why we are sanctioning RSF commanders who we have reasonable grounds to suspect have been responsible for, engaged in, provided support for or promoted the commission of these serious violations of international humanitarian law. We will impose travel bans, director disqualifications and asset freezes. This will ban these individuals from entering the UK, and stop them from being able to form, manage or promote a UK company or interact in any way with the UK economy. We are sanctioning:
My noble Friend the Minister of State for International Development and Africa (right hon. Baroness Chapman of Darlington) has today made the following statement:
When this Government came into power, we were clear that a new kind of relationship with African countries was long overdue. We inherited an approach that reflected the past rather than being fit for the future. That is why this Government committed in their manifesto to deliver a new approach to the African continent for mutual long-term benefit, recognising Africa’s growing importance to the UK’s domestic missions and plan for change.
We were clear too that reframing our relationship was not something to cook up here in London and then package up as a shared approach. Some have spoken the language of partnership that is not borne out in practice, without being clear and up front about our own interests and what we want from the relationship. So we launched a five-month listening exercise, hearing from Governments and over 600 organisations, from civil society and diaspora communities, from businesses and universities, about what they valued and wanted to see from Britain. There was a clear common message: African nations want respectful, long-term partnerships that deliver real change for people’s lives.
Today, the Government are fulfilling our manifesto commitment, marking a significant milestone in the UK’s partnership with African countries. The UK’s new approach is shaped by African leadership, ideas, and energy—aligning with the steps that the UK and African nations are already taking to unlock new growth opportunities, lead climate action, drive innovation, and push for reform to the international system—and brings this together with UK strengths. It is consistent with the principles of our modernised approach to international development, recognising we are not just donors. We are partners, investors, and reformers.
Mauritius has also confirmed that civil status documents issued by the Government of Mauritius will continue to record the place of birth as the Chagos archipelago for all of those born there. Where, for any reason, this has not been the case, the Government of Mauritius will review and amend the documents as necessary.
Mauritian Criminal Code Amendment
On 29 October, the Mauritius Criminal Code (Amendment No.2) Act 2025 came into force, repealing section 76B of the Mauritian criminal code and removing the offence of
“misrepresenting the sovereignty of Mauritius by producing, distributing, supply or marketing any coin, stamp, official map or official object or document.”
Concerns had been raised that Chagossians might face prosecution for expressing their affiliation with the UK. Although no one was ever prosecuted under this law, we recognise the impact it was having on the Chagossian community and welcome the steps taken by the Mauritian Government to have section 76B of the Mauritian criminal code repealed.
Heritage Visits to the Chagos Archipelago
Both the UK Government and the Republic of Mauritius recognise the importance of heritage visits for the Chagossian community and remain committed to facilitating a programme of heritage visits to the Chagos archipelago, including Diego Garcia. We will work together to resume a programme of visits to the archipelago.
Chagossian Support Programme—Supporting Chagossians in our Communities
Separate to the treaty, the Government are increasing support for Chagossians living in the UK through both new and existing initiatives. This includes support for newly arrived British citizens and a wide range of projects that will benefit the Chagossian community.
Chagossian Contact Group
The Chagossian contact group provides Chagossians with a role in decision-making on the UK Government’s support for their community. On 11 November, we committed to exploring ways to enhance the group by increasing its transparency and frequency, provided that the contact group’s existing members agreed. FCDO officials have discussed this with contact group members, who are now consulting with the wider community ahead of making decisions. We will provide a further update once these are received.

Abdul Rahim Hamdan Dagalo—deputy leader of the RSF, and brother of RSF leader, General Mohamed Hamdan Dagalo Moussa, “Hemedti”. He is or has been responsible for engaging in, providing support for or promoting the commission of serious violations of international humanitarian law in Sudan, including the mass killings of civilians; ethnically targeted executions; sexual violence, including gang rape; abductions for ransom; widespread arbitrary detentions; and attacks on health facilities, medical staff and humanitarian workers. Acting in global resolve with partners such as the US, Canada and the EU, which have all previously sanctioned Abdul Rahim Hamdan Dagalo, this sends a strong message of international condemnation for his actions.
Gedo Hamdan Ahmed, “Abu Nashuk”—RSF commander for the north Darfur section. He is or has been responsible for engaging in, providing support for, or promoting the commission of serious violations of international humanitarian law in Sudan, such as the mass killings of civilians; ethnically targeted executions; sexual violence, including gang rape; abductions for ransom; widespread arbitrary detentions; and attacks on health facilities, medical staff and humanitarian workers.
Tijani Ibrahim Moussa Mohamed, “Al Zeir Salem”—RSF field commander. He too is or has been responsible for engaging in, providing support for, or promoting the commission of serious violations of international humanitarian law in Sudan, including the deliberate targeting of civilians in El Fasher.
Al-Fateh Abdullah Idris “Abu Lulu”—brigadier general of the RSF, dubbed “the butcher of El-Fasher” for claiming to have killed over 2,000 people. He is being sanctioned for his involvement in serious violations of international humanitarian law in Sudan and the systematic campaign of violence against civilians in El Fasher.
The Sudanese sanctions regime contains a humanitarian assistance exception to the asset freeze. We do not expect these designations to have humanitarian impacts and will monitor this closely.
In addition to these sanctions, the UK is stepping up our response to the crisis in Sudan with an additional £21 million. This will fund support including food, shelter, health services to those most in need, and protection for women and children in some of the hardest-to-reach areas. This lifeline will empower aid organisations to reach 135,000 people with essentials like food, medical care, and emergency shelter, as well as enable them to keep hospitals running and reconnect families torn apart by conflict. The overall UK aid commitment to Sudan this year rises as a result to £146 million, delivering lifesaving aid to over 800,000 people, and underscoring the unwavering commitment to stand with the Sudanese people and meet humanitarian needs.
As the UK, we are doing all we can politically and diplomatically to end the fighting, prevent future atrocities, protect civilians and deter the perpetrators by bringing accountability and justice—however long it takes. We are leading the charge to bring accountability to those committing heinous atrocities, at the UN and the International Criminal Court, for all to see. We will not let these horrors go unanswered.

Responding to the consultation, the UK’s new approach provides a high-level framing to guide the Government’s long-term engagement with African partners, reaffirming the shift from paternalism to a partnership of respect and equality. It does so over seven areas of shared interest.
First, we are moving from donor to investor. We will go further to unlock investment and trade, helping African and British businesses create quality jobs, economic opportunities, and prosperity. Our partnerships will place mutual growth at the centre. We will back the African continental free trade area, supporting its implementation and the opportunities it creates, and strengthen UK-Africa relations through ongoing tariff reviews, building on the developing countries trading scheme and network of economic partnership agreements. We will support the development of local capital markets, mobilise private capital to invest sustainably, and scale up promising African enterprises. The UK’s investment vehicles—British International Investment, FSD Africa Investments, and UK Export Finance—will continue to drive this innovative agenda. As a long-standing partner of the African Development Bank, we will continue to strengthen our collaboration with Africa’s leading financial institution. And we are proud to be co-hosting with Ghana the 17th replenishment of the African Development Fund, using our convening power to scale up private capital for Africa’s development priorities.
Secondly, we are working together on the challenges of migration. Migration should be fair, managed, and controlled. But this is undermined by illegal migration that harms both the UK and African partners, funds organised criminal gangs, and puts lives at risk. We will provide humanitarian support to alleviate suffering; help enable protection for displaced people in their regions of origin; and work together to disrupt criminal networks and facilitate returns. We will be unapologetic in pressing for high ambition and clear progress against these priorities. Recognising the UK visa system can seem hard to navigate, we are engaging with African businesses to improve understanding, including uptake of the global partner programme, helping businesses travel, build ties, and stimulate investment.
Thirdly, we are advancing shared interests on climate, nature, and clean energy. Despite its abundant natural resources, Africa has the lowest levels of modern energy access. And despite contributing least to global emissions, African nations are among those shouldering the greatest climate risks. Therefore, we must go further to invest in renewables, protect biodiversity, and ensure climate finance reaches those who need it most, creating more opportunities for African countries by growing the scale and quality of carbon markets. We will back African initiatives such as Mission 300 to connect 300 million people to electricity by 2030. We will work with African scientists to protect the world’s largest forest carbon stores in the Congo basin and mobilise finance through the Belem call to action. And we look forward to supporting further African leadership on climate as Ethiopia hosts COP32 in 2027.
Fourthly, we want to collaborate for peace and stability, the foundations of prosperity. We will continue to work closely with the African Union and other partners to support African efforts to “silence the guns” and promote post-conflict recovery. This includes urgent work to support an end to the horror of the current war in Sudan. We will continue to work with African partners to help push the warring parties towards a ceasefire, to supply the lifesaving humanitarian aid where needed and to call out and avert, together, atrocities like in El Fasher, where we know rape has been used systematically as a weapon of war. The UN’s humanitarian chief has correctly called this the epicentre of human suffering. We are determined to support Sudan and ensure the world does not forget this devastating conflict. Beyond Sudan, we are supporting vital peacebuilding efforts in the Great Lakes region and working on conflict prevention with countries such as Nigeria, Ethiopia and Somalia. This is part of a wider push to build security partnerships to tackle regional instability and shared threats, champion respect for international humanitarian law, stand up for freedom of religion and belief, and go much further to tackle violence against women and girls.
Fifthly, we are strengthening systems that support people and growth. This is about strengthening the systems that build human capital—the engine of sustainable, inclusive growth. Rather than providing piecemeal funding to individual services, we will work with partners to improve whole systems for health and nutrition, education, and social protection. We will invest in vaccine manufacturing, disease prevention, and sexual and reproductive health and rights. Last month, the UK announced in South Africa its pledge of £850 million to the Global Fund—a pledge that stands to save over 1 million lives, prevent 20 million cases of HIV/AIDS, TB and malaria, and deliver over £10 billion in economic returns. This investment demonstrates the UK’s commitment to global health, gender equality, multilateralism, and modern development partnerships. We are applying the same principles to helping African countries become financially self-reliant, harnessing UK expertise in tax, finance, and technology. Next year, the Foreign Secretary will host the illicit finance summit in London, convening a diverse coalition of Governments, multilateral organisations, the private sector, and other key stakeholders to tackle criminal and corrupt wealth.
Sixthly, we are championing African voices in global decision-making. We will amplify and work alongside African calls for fairer representation in global forums, ensuring African priorities shape the rules and outcomes that matter most. This is why the UK strongly advocated for the establishment of a third seat for sub-Saharan Africa at the IMF board, and why we continue to call for lower-income countries to have greater voting power at the World Bank. It is also why we look forward to the establishment of a borrowers’ platform, following agreement at the financing for development conference in Seville. As we look ahead to our G20 presidency in 2027, we will continue to work towards further reforms to the debt architecture to tackle unsustainable debt following the G20 ministerial declaration on debt sustainability in October, so that African countries have a greater stake in the decisions that affect them.
Lastly, we are supporting innovation and cultural partnerships. From AI and digital skills to music, sport, and design, there is enormous potential to deepen our ties across science, technology, and the creative industries. At South Africa’s science forum in November, we launched our first UK-South Africa AI policy training programme to establish a cohort of AI-savvy diplomats and officials from both countries, drawing on the expertise of leading UK and South African universities. Our forthcoming soft power collaboration will support alumni networks across the UK and Africa. We will maintain scholarships and strengthen our enduring research and education partnerships. These connections are not just economic—they are human, and they are powerful. One milestone is Imperial College London opening its first African hub in Ghana last year, marking a major step forward in UK-Africa scientific collaboration. This new centre will support fellowships in AI and climate science, accelerating joint research and innovation across medical diagnostics, vaccine research, and sustainable cities.
This adds up to a new kind of partnership. One that works with African leadership. One that is inclusive and respectful and strong enough to work through difficulties and disagreements. Our high commissions and embassies will be at the forefront of embedding this approach—in spirit and content—and we will take it forward into the UK’s G20 presidency in 2027. UK Ministers will be out there, on the continent, championing these principles, strengthening coherence across our partnerships, and backing diverse African voices to shape our work.
