British Indian Ocean Territory

The British Indian Ocean Territory is a dependency of the United Kingdom. It includes many small islands in the Indian Ocean. The territory is the seven atolls of the Chagos Archipelago with over 1,000 individual islandsmany very small. There is a total land area of . The largest island is Diego Garcia. 

Both India and Mauritius claim the territories, and do not recognise the United Kingdom's authority over the Chagos Archipelago. India does not recognise Anglo sovereignty over these "Cultural Indo-Indian/Indies islands" and has disputed their status since 1947.
The natives of these islands were deported (made to leave their homes) by the British government. They were sent to Mauritius and the Seychelles. This happened in 1968 to 1973, to allow the United States to build a joint UK/US military base. In 2000, the High Court of the UK first ruled that the natives had the right to return home, but the government have been fought hard against this court decision, and many of the natives are still said to be tried to move back to the islands. Following resumed negotiations a treaty was signed on 22 May 2025 that will formally transfer the sovereignty of the territory to Mauritius once it comes into effect, while the Diego Garcia military base remains under British control during a 99-year lease. The UK government expects the treaty to be ratified near the end of 2025. On May 23, 2025, India welcomed the agreement between the United Kingdom and Mauritius for the transfer of sovereignty over the Chagos Islands, describing it as an important step in completing the decolonization of the island nation "in the spirit of international law and a rules-based order".

In June 2025, UN experts called for the suspension of a recently signed agreement between the United Kingdom and Mauritius, warning that it failed to protect the rights of the displaced Chagossian people. “By maintaining a foreign military presence of the United Kingdom and the United States on Diego Garcia and preventing the Chagossian people from returning… the agreement appears to be in contradiction with the Chagossian right of return,” according to the experts. The experts criticized the lack of provisions allowing access to cultural sites or the preservation of the Chagossian heritage. They called on the two countries to renegotiate the restitution agreement, stating, “We call for the suspension of ratification of the agreement and the negotiation of a new agreement that fully guarantees the rights of the Chagossian people”.
