Here are the latest publicly reported developments on the Chagos Archipelago as of May 2026.
Sovereignty and resettlement talks continue between the United Kingdom and Mauritius. In 2024 the UK indicated it would transfer control of the Chagos Islands to Mauritius, a move connected to broader decolonisation and sovereignty discussions, with implications for Chagossian communities. These developments remain politically sensitive and are subject to ratification and national legal processes in multiple jurisdictions.[5][9]
Mauritian authorities have signaled plans to establish a Marine Protected Area (MPA) around the Chagos Archipelago as part of asserting national oversight of the waters, while the U.K. maintains a continuing military presence on Diego Garcia. The future of the MPA and related conservation efforts intersect with sovereignty negotiations and potential resettlement schemes for Chagossians.[3][5]
News outlets in late 2024–early 2026 have reported on attempts by Chagos islanders to influence or block the UK–Mauritius transfer through settlements or visits to the archipelago, highlighting ongoing diaspora involvement and legal-political complexity around resettlement and access to Diego Garcia. Several articles discuss the humanitarian and legal dimensions for Chagossians, including residency rights and eligibility for return (excluding Diego Garcia, which hosts the U.S.-UK military base) under certain proposed arrangements.[8][10][3][5]
Broad context: multiple sources cover this issue from historical, legal, and geopolitical angles, including UN-related statements about the status of the Chagos Islands and ongoing debates about sovereignty, decolonisation, and the status of the Chagossian community.[5]
