UK to hand over sovereignty of Chagos Islands to Mauritius after decades-long dispute

The UK will hand over sovereignty of the remote Chagos Islands to Mauritius after a decades-long dispute.

The deal to transfer the Indian Ocean archipelago to Mauritius includes the tropical atoll of Diego Garcia, home to a military base used by the UK and the US that plays a crucial role in the region’s stability and international security.

Under the agreement, the base will remain under UK and US jurisdiction for at least the next 99 years.

The UK government said that the treaty would “address wrongs of the past and demonstrate the commitment of both parties to support the welfare” of Chagossians – the native people of the islands.

Since 1971, only Diego Garcia has been inhabited – by US military employees – after the UK expelled the Chagossians at the request of the US.

The islands had been a dependency of Mauritius when it was a French colony, but both were handed to the UK in 1845. Mauritius gained independence from the UK in 1968 and has since claimed the Chagos archipelago as Mauritian.

Foreign Secretary David Lammy said: “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.

“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, a close Commonwealth partner.”
