Chagos Archipelago is a territory of United Kingdom
Today, it is continuing a dispute about a set of them in the middle of the Indian Ocean, known as the Chagos Archipelago. Formally the British Indian Ocean Territory (BIOT), the archipelago was administered from Mauritius in the days of empire and was detached in the lead-up to Port Louis’ independence from London in 1968. The Chagos Archipelago contains Diego Garcia, now home to a strategically positioned US military base, whose existence was made possible by the forced deportation of those living there, the Chagossians. [...] This 2019 opinion states that the United Kingdom had no authority to sever the archipelago from Mauritius, and thus control over it should be ceded from London to Port Louis. Despite this ruling, however, the United Kingdom has been reluctant to act on its obligations as laid out by the ICJ. [...] Crucially, the current Jugnauth government has stated that "the end of UK administration has no implications for the US military base at Deigo Garcia, which Mauritius is committed to maintaining". It will allow Chagossians to return only to the other islands in the archipelago.
