Maldives asks Britain to reopen Chagos sovereignty talks

Malé challenges the existing diplomatic framework

Maldives President Mohamed Muizzu has asked British Prime Minister Andy Burnham to reopen discussions over the sovereignty of the Chagos Archipelago, introducing a fresh claimant into a process Britain has conducted with Mauritius. In a letter publicised on September 8, Muizzu argued that the Maldives should have been consulted before London agreed to transfer sovereignty to Mauritius. The request does not itself alter the legal status of the islands, but it creates a new diplomatic complication around one of the Indian Ocean’s most strategically important territories.

The Maldivian position rests on claimed historical ties, geographic proximity and involvement in marine conservation and scientific work. The islands lie roughly 500 kilometres from the Maldives, while Mauritius is much farther away. Britain’s Foreign Office, as reported by Al Jazeera, maintained that sovereignty is a matter between the United Kingdom and Mauritius and pointed to negotiations launched with Port Louis in 2022. That response indicates London has not accepted Malé as a party to the existing sovereignty process.

A sovereignty transfer built around Diego Garcia

Britain and Mauritius signed their agreement on May 22, 2025. The published treaty recognises Mauritian sovereignty over the whole archipelago, including Diego Garcia, while preserving long-term operation of the joint UK-US military facility there. A separate British government statement described the base as central to national and allied security. Diego Garcia’s position between Africa and Asia gives it unusual logistical value for surveillance, air operations and maritime security across the Indian Ocean and adjoining regions.

Muizzu’s intervention matters because it challenges the bilateral premise of the agreement without presenting a negotiated alternative for the base or for Chagossian interests. It also arrives while implementation remains politically contested. The British government’s treaty register continued to list the agreement in its official materials, and its environmental framework stated that sovereignty would transfer when the treaty entered into force. Until then, Britain continues administering the territory, making the timing and legal status of implementation central to any reopened discussion.

The immediate question is whether London responds only by restating its position or offers a separate consultation mechanism with Malé. Mauritius is also likely to resist any process that reopens the sovereignty settlement it negotiated with Britain. Any change would have to address the treaty, the continued operation of Diego Garcia, environmental management and the rights and views of displaced Chagossians. For now, the verified development is a formal Maldivian request and a British refusal to treat sovereignty as a trilateral issue, not the reopening of negotiations.
