On 22 May the Diego Garcia treaty was signed and laid before the House. As the Defence Secretary told the House on the day of signature, the treaty secures the strategically important UK-US military base on the island of Diego Garcia. The base is essential to the security of the UK and our key allies, and to keeping British people safe. 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 the introduction of primary legislation to establish the trust fund. The Mauritian Bill confirms the principle that the trust fund will be operated for Chagossians and 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 Chagossians, ensuring majority representation. The chair of the trust fund will be a Chagossian, selected by the Chagossian members. Following extensive representations and engagement by this Government, the Mauritian Bill also 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 that the trust fund reflects the full spectrum of perspectives within the Chagossian community. 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 the 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 to the children of a parent who was born on the archipelago before that date. As of April 2025, 94% of Chagossians with British nationality also had Mauritian citizenship. However, any UK-based Chagossian who does not hold Mauritian citizenship and who meets the criteria will be eligible for it and therefore able to participate in any future programme of resettlement. All Chagossians will remain eligible for British citizenship under the current citizenship pathway, and they will be able to hold both British and Mauritian citizenship.
