Britain agrees Chagos Island sovereignty deal with Mauritius

London: Britain said on Thursday it would give up sovereignty of the Chagos Islands to Mauritius in a deal that would allow people displaced decades ago to return home while London retains use of the UK-US military base on Diego Garcia.

Britain said that the operation of Diego Garcia, a strategic military base jointly operated with the United States, was protected by the agreement, which also allows Mauritius to resettle the rest of the islands after its population was displaced.

"This government inherited a situation where the long-term, secure operation of the Diego Garcia military base was under threat, with contested sovereignty and ongoing legal challenges," British Foreign Minister David Lammy said in a statement.

"Today’s agreement secures this vital military base for the future. It will strengthen our role in safeguarding global security, shut down any possibility of the Indian Ocean being used as a dangerous illegal migration route to the UK, as well as guaranteeing our long-term relationship with Mauritius."

Britain, which has controlled the region since 1814, detached the Chagos Islands in 1965 from Mauritius - a former colony that became independent three years later - to create the British Indian Ocean Territory.

In the early 1970s, it evicted almost 2,000 residents to Mauritius and the Seychelles to make way for an airbase on the largest island, Diego Garcia, which it had leased to the United States in 1966.

The World Court said in 2019 that Britain should give up control of the islands and said it had wrongfully forced the population to leave in the 1970s to make way for a US air base.

In a joint statement, Britain and Mauritius said that the political agreement had the support and assistance of the United States and India.
