Muizzu asks Burnham for talks on Chagos before the UN week

Maldives President Mohamed Muizzu wrote to British Prime Minister Andrew Burnham on 8 September and asked for talks on the Chagos Archipelago. His office said the letter recorded “deep disappointment” that London had negotiated a handover to Mauritius without consulting Malé, and invited Burnham to “meaningful dialogue” on sovereignty.

Britain signed an agreement with Mauritius in May 2025 to transfer the islands, then lease back Diego Garcia, the site of a joint UK-US air base. Donald Trump later called the deal “a great act of stupidity.” In April 2026 the Burnham government, still new in office, put the legislation on hold. Foreign Office minister Uma Kumaran told MPs this month that the pact would give “legal certainty” for the base. Mauritius has said it may press the issue at the UN General Assembly later in September, in part because the first lease payment has not arrived.

Muizzu’s claim is older than the 2025 text. Malé says the archipelago, which it calls Foalhavahi, sits about 500 kilometres from the Maldives and more than 2,000 kilometres from Port Louis. Officials cite a sixteenth-century map associated with King Hassan IX and graves with Dhivehi inscriptions as evidence of historical presence. They also point to Maldivian work on marine research in the same waters. India has welcomed the UK-Mauritius deal as the last step in Mauritius’s decolonisation. The Maldives has not.

The letter is timed to a bilateral calendar. Officials in Malé said UK-Maldives meetings are due later this month. Muizzu asked Burnham to “rectify this oversight by your predecessor” and said a “renewed partnership” could help Indian Ocean stability “at a time of increasing global uncertainty.” He did not demand that Britain abandon Mauritius. He demanded a seat that was never offered.

That seat matters because Diego Garcia is not a museum piece. The atoll hosts long-range aircraft, pre-positioned stocks and a lagoon deep enough for large ships. Any change in the legal title of the surrounding islands feeds into basing rights, environmental rules and the status of Chagossians who want to return. A three-party argument is harder to close than a two-party lease.

Burnham has not published a reply. His government has signalled that it still prefers the Mauritius route. That preference collides with two other facts. Washington has already called the original bargain a mistake. Malé has now put a competing title on paper in the week before the UN gathering.

Geography is the part of the file that does not move. The Chagos group sits in the central Indian Ocean, astride routes between the Gulf, East Africa and South-East Asia. Mauritius argues law and decolonisation. The Maldives argues distance, language and an old map. Britain argues that only a deal with Mauritius keeps the base usable. Those three sentences do not resolve one another.

If Burnham meets Muizzu, the minimum outcome is a record that Malé was heard. The maximum is a delay that leaves the 2025 treaty in the drawer through the UN week. If he does not meet, Muizzu can say the “oversight” continues.

The Chagossian community, scattered in Mauritius, Seychelles and Britain, has its own claim to return. That claim is not in Muizzu’s letter. It will sit in the same room if talks start. The base, the lease, the graves and the map are now one file.

Malé’s distance argument is the easiest part of the letter to check on a chart. Five hundred kilometres is not a legal title. Two thousand kilometres is not a waiver of one. What the letter does achieve, on the day it was sent, is to stop the UK-Mauritius track from looking like the only conversation in the ocean. Burnham now has to answer two capitals, not one, before he goes to New York.
