What is the Chagos Islands dispute between Mauritius and the UK?β
The Chagos Archipelago, also known as the British Indian Ocean Territory (BIOT), was separated from Mauritius by Britain in 1965 before Mauritius gained independence in 1968. Mauritius argues this separation was illegal under international law. Both the International Court of Justice (2019) and a UN tribunal (2021) issued rulings supporting Mauritius's claim. The islands are home to Diego Garcia, a key US-UK military base, which complicates the sovereignty negotiations.
Has a deal on Chagos sovereignty been agreed between Mauritius and the UK?β
A framework agreement in principle was announced in 2022, under which the UK would transfer sovereignty of the Chagos Islands to Mauritius, while the Diego Garcia military base would continue operating under a long-term lease. However, the final deal has not yet been signed, and negotiations are ongoing, with Prime Minister Ramgoolam set to meet UK PM Andy Burnham on Monday to advance discussions.
Who are the Chagossians?β
The Chagossians are the descendants of the indigenous population of the Chagos Islands, who were forcibly removed by British authorities between 1967 and 1973 to make way for the construction of the Diego Garcia military base. Many were relocated to Mauritius and the Seychelles. Their right to return to the islands is a central humanitarian element of the ongoing sovereignty negotiations.
