Disputes over the British Indian Ocean Territory: a survey
Between 1968 and 1973 the British Government cleared the entire Chagos Archipelago of its inhabitants, opening the way for a US military base on the biggest island, Diego Garcia. The Archipelago was made a British overseas territory, the British Indian Ocean Territory (BIOT). Two main disputes have arisen from these events. One has been between the Chagos Islanders and the British Government over the legality of the former’s removal and whether they have a right to return. The other has been between the UK and Mauritius about sovereignty over the BIOT. The UK has said that it will cede sovereignty to Mauritius once the BIOT is no longer required for defence purposes.
