UK puts Chagos Islands handover on hold after US pushes back

The UK government has put its plan to return the Chagos Islands to Mauritius on hold, citing renewed pressure from the United States. A bill that would have formalized the handover has been paused, with officials acknowledging it won't pass before the end of the current legislative session. The decision comes after the US, particularly President Donald Trump, voiced sharp opposition to the agreement.

The Chagos archipelago, located in the Indian Ocean, has been a point of diplomatic tension for decades. The UK separated the islands from Mauritius in 1965, just before the island nation gained independence. Soon after, the US built a major military base on Diego Garcia, the largest island in the chain. That base remains strategically vital for military operations in the Middle East and Asia.

Recent efforts to resolve the long-standing sovereignty dispute had gained momentum, with both UK and Mauritian officials believing a deal was within reach. But the US, which had previously signaled cautious support, reversed course. Trump publicly slammed the agreement in a social media post, calling it an 'act of great stupidity' and warning it would weaken national security.

While the UK maintains that the Diego Garcia base would remain under joint control for at least 99 years under the proposed deal, US officials have expressed doubts about long-term guarantees. The base supports surveillance, logistics, and rapid deployment capabilities, and any uncertainty about its future has made US leaders nervous-especially in a tense geopolitical climate.

Backlash from human rights groups and Chagossian descendants has been swift. Many were forcibly removed from the islands in the 1960s and 70s, and for decades have campaigned for the right to return and for recognition of Mauritius' sovereignty. Advocates say the latest delay is another broken promise, prolonging a painful chapter of colonial legacy.

UK officials say talks are still ongoing and that the handover remains a goal, but the political reality has shifted. With the US now firmly opposed, London appears unwilling to move forward unilaterally. Diplomats on both sides are expected to continue negotiations, though no new timeline has been set.

The pause leaves thousands of Chagossians in limbo and underscores how strategic military interests can override decolonization efforts. While the UK has acknowledged the moral weight of returning the islands, it's clear that alliance politics-and one president's blunt criticism-can still change the course of history.
