The United Kingdom has put on hold legislation to transfer sovereignty over the Chagos Islands to Mauritius. The pause follows objections from the United States, which operates a major military base on Diego Garcia and must approve any change to its 1966 defence agreement with the UK. This development delays hopes of resettlement for the displaced Chagossian community and prolongs a long‑running decolonisation dispute.
Historical background
The Chagos Archipelago consists of more than 50 tiny islands in the Indian Ocean. It was separated from Mauritius by the British in 1965 to form the British Indian Ocean Territory (BIOT). Between 1967 and 1973 Britain forcibly removed over 1,500 Chagossians from their homeland to make way for a US naval and air base on Diego Garcia. The islanders were relocated to Mauritius, Seychelles and the UK and have campaigned for return and compensation ever since.
Recent negotiations
In 2019 the International Court of Justice issued an advisory opinion stating that Britain’s continued administration of the archipelago was unlawful and that the islands should be returned to Mauritius. The UN General Assembly adopted a resolution demanding compliance. In 2025 the UK and Mauritius negotiated a draft treaty envisaging Mauritian sovereignty with a long‑term lease of Diego Garcia to the US. However, the US Congress must consent to amending the 1966 UK–US agreement.
Current developments
- US opposition: The administration of US President Donald Trump has signalled it will not support any deal that could jeopardise the strategic value of the Diego Garcia base. Washington believes the base is vital for operations in the Indo‑Pacific region.
- UK response: The British government has paused the sovereignty bill and stated that it will only proceed in consultation with its security partners. It argues that maintaining long‑term security arrangements is paramount.
- Mauritius’ stance: Mauritian leaders continue to press for decolonisation and resettlement of displaced islanders. They describe the pause as a setback but pledge to pursue the issue through diplomatic and legal channels.
Significance
- Decolonisation and human rights: The Chagos case highlights unresolved colonial legacies and the rights of indigenous peoples to return to their ancestral lands.
- Strategic concerns: Diego Garcia is a key logistics and surveillance hub for US and UK forces. Any change in sovereignty has implications for power projection in the Indian Ocean.
- Diplomatic relations: The dispute involves three countries—Mauritius, the UK and the US. Balancing legal obligations and security interests requires delicate negotiations.
