Chagos Islands sovereignty has once again become a point of diplomatic friction between the Maldives and Britain, after President Mohamed Muizzu wrote to British Prime Minister Andy Burnham asking him to reopen talks on the issue. A spokesperson for the Maldivian president said in a statement on Tuesday that Muizzu was deeply disappointed that Britain did not consult the Maldives before his predecessor, Keir Starmer, agreed to cede sovereignty of the Indian Ocean archipelago to Mauritius.
Why President Mohamed Muizzu Is Reopening the Chagos Islands Sovereignty Question
According to a statement released by the Maldivian presidential office, Muizzu emphasised the importance of meaningful dialogue between the UK and the Maldives on matters concerning the sovereignty of the Chagos archipelago. His letter expressed the Maldives’ concerns regarding Britain’s decision to proceed with the handover of the islands to Mauritius, and urged Burnham to rectify what Muizzu described as an oversight by his predecessor. The approach signals that Malé sees the change in British leadership as an opportunity to press a claim it has raised, without success, for several years.
The Deal With Mauritius and the Diego Garcia Base
The dispute centres on an agreement finalised in May 2025, under which Starmer’s government agreed to transfer sovereignty of the Chagos Islands to Mauritius. Under the terms of that multibillion-dollar arrangement, Britain retains control of the strategically important Diego Garcia military base, which it operates jointly with the United States, through a lease running for 99 years. For the UK and its allies, the deal was designed primarily to secure the long-term future of the base, a hub for military logistics in the Indian Ocean, while formally addressing longstanding questions about the archipelago’s colonial-era separation from Mauritius.
Britain’s Response to the Maldives’ Objection
A spokesperson for Britain’s foreign office responded to the Maldives’ latest approach by noting that London continues to speak with its counterparts in the Maldives regularly about a range of issues. However, the spokesperson made clear that the question of sovereignty over the Chagos Archipelago remains a matter for the UK and Mauritius alone, pointing out that the previous government launched negotiations with Mauritius specifically, rather than with the Maldives, when talks began in 2022. That position leaves Muizzu’s request for reopened talks facing firm resistance from London’s official line, even as the diplomatic exchange continues.
A Long-Running Diplomatic Dispute
This is not the first time the Maldives has raised objections through formal channels. The country previously wrote to the British government in November 2024 and again in January 2026 to formally object to the Mauritius deal, arguing that Britain’s decision to proceed in consultation with Mauritius alone, without accounting for Maldivian interests, was deeply concerning.
The Maldives has said it does not recognise the transfer of the Chagos Archipelago to Mauritius on those grounds, and Muizzu has previously told a UK deputy prime minister directly that any transfer of the archipelago must take Maldivian interests into account.
Geography at the Heart of the Maldives’ Claim
Central to the Maldives’ position is its geographic proximity to the disputed islands. The Maldives lies roughly 500 kilometres from the Chagos archipelago, compared with a distance more than four times as great between the islands and Mauritius. Malé has cited this proximity, together with what it describes as historical and administrative ties to the archipelago, as the basis for its claim that it should have been consulted before sovereignty was transferred.
British officials have countered that international courts have already examined the question of sovereignty and ruled in Mauritius’s favour, a position that has so far limited how much weight London has given to the Maldives’ objections.
What Comes Next for Chagos Islands Sovereignty
With Britain’s foreign office reaffirming that the matter rests between London and Port Louis, the prospects for a formal reopening of Chagos Islands sovereignty talks with the Maldives appear limited in the near term. Even so, Muizzu’s latest letter suggests Malé intends to keep raising the issue with each change in British leadership, betting that sustained diplomatic pressure, if not a change in the underlying legal position, may eventually secure the Maldives a seat at a negotiating table it has so far been kept away from.
