Britain’s Chagos Islands Deal with Mauritius Stalls After U.S. Withdraws Support
A long-negotiated agreement to transfer the Chagos Islands from British to Mauritian sovereignty has been indefinitely suspended after the Trump administration withdrew its support for the deal, British officials confirmed Saturday.
The agreement, which would have included a 99-year lease arrangement for the strategically vital Diego Garcia military base, has run out of time to complete its legislative process in the current session of Parliament. The bill is not expected to appear in the upcoming legislative agenda to be announced by King Charles III on May 13.
“Diego Garcia is a key strategic military asset for both the UK and the US,” the British government said in a statement. “Ensuring its long-term operational security is and will continue to be our priority — it is the entire reason for the deal. We continue to believe the agreement is the best way to protect the long-term future of the base, but we have always said we would only proceed with the deal if it has US support.”
The collapse of the agreement marks another point of tension between Prime Minister Keir Starmer’s government and the administration of President Donald Trump. In January, Trump reversed his initial support for the transfer, calling it “an act of GREAT STUPIDITY” in a social media post.
Simon McDonald, former head of Britain’s Foreign Office until 2020, said the government “had no other choice” but to shelve the agreement. “When the president of the United States is openly hostile, the government has to rethink. So this agreement, this treaty will go into the deep freeze for the time being,” he told the BBC.
The remote archipelago of more than 60 islands, located in the Indian Ocean south of the Maldives, has been under British control since 1814. The Diego Garcia base has served as a crucial launching point for American military operations from Vietnam to Iraq and Afghanistan, and as a base for U.S. bombers in operations against Iranian targets.
Relations between the U.S. and U.K. have been strained in recent months over military cooperation. Starmer initially blocked American planes from using British air bases for strikes against Iran, though he later permitted the use of bases in England and on Diego Garcia for limited operations targeting Iranian missile sites. Trump subsequently criticized Starmer, saying he was “not Winston Churchill,” and mocked the Royal Navy.
The agreement with Mauritius had been presented by the Starmer government as a pragmatic solution to mounting international pressure. In recent years, both the United Nations General Assembly and the International Court of Justice have urged Britain to return the islands to Mauritius, citing decolonization principles. Under the deal, Britain would have formally transferred sovereignty while securing long-term operational control of the military facility.
Opposition to the agreement has been fierce from Britain’s Conservative Party and Reform UK, who argue that relinquishing sovereignty could potentially expose the islands to interference from China and Russia. These opposition parties reportedly encouraged the Trump administration to withdraw support.
The deal has also faced criticism from Chagossian communities. An estimated 10,000 islanders and their descendants, now living primarily in Britain, Mauritius, and the Seychelles, have expressed concern that they weren’t adequately consulted. Many were forcibly displaced from Diego Garcia between the 1960s and 1970s to make way for the military base and have fought unsuccessfully in UK courts for decades for the right to return.
British officials maintain they still hope the agreement can be revived, though any progress now appears contingent on securing renewed American support. In the meantime, the sovereignty dispute will likely continue in international forums, with Mauritius pressing its claim and Britain maintaining its position that the military base’s security remains paramount.
