Andy Burnham seeks to recast Chagos Islands deal amid US opposition

Prime Minister Andy Burnham has indicated his intention to "recast" the UK’s agreement to cede control of the Chagos Islands after facing significant resistance from the United States. The original deal, negotiated by former Prime Minister Keir Starmer, would have transferred sovereignty of the territory to Mauritius while maintaining a 99-year lease for the joint UK-US military base on Diego Garcia. However, the agreement has remained in limbo following vocal opposition from President Donald Trump, who described it as a "terrible deal" during a meeting with Burnham in New York.

Rethinking the Andy Burnham Chagos Islands agreement

Speaking to the Economist, the Prime Minister stated that his administration is currently engaged in discussions with American officials to find an arrangement that addresses their security concerns. Burnham suggested that the UK could look toward the model used in America’s Greenland deal with Denmark as a potential framework. Under that arrangement, Greenland remains Danish territory, but the U.S. is permitted to maintain a significant military presence while preventing adversaries from establishing bases on the island.

The UK is attempting to renegotiate the Chagos Islands sovereignty deal to satisfy American security requirements.

Defence Secretary Wes Streeting confirmed that the British government has suspended financial payments to Mauritius while a compromise is sought. Streeting emphasized that the current deal cannot proceed without American support, noting that the government must secure an agreement that satisfies the U.S., the UK, and Mauritius. The original treaty included provisions for Mauritius to receive £165 million over the first three years, followed by £120 million annually thereafter.

Beyond the Chagos negotiations, Burnham addressed his recent attendance at the Commonwealth heads of government summit in Antigua. He noted that his government has made progress on the issue of slavery reparations by opening the possibility of a formal apology. Looking ahead, the Prime Minister is preparing for an international summit in Manchester next year, where he confirmed that Vladimir Putin will be barred due to existing sanctions, while Chinese President Xi Jinping will be welcomed. Additionally, Burnham is finalizing a "10-year plan" for the UK, which he expects to be a substantial and compelling roadmap for the country’s economic future, potentially to be unveiled in early 2025.

Why it matters

The uncertainty surrounding the Chagos Islands deal highlights the complex geopolitical balance between the UK’s sovereignty goals and its strategic military partnership with the United States. The outcome will determine the future administration of the islands and the ongoing operational status of the Diego Garcia base, which serves as a critical defense asset.
