Trump Criticizes UK Chagos Islands Deal: Calls It 'Terrible'

• President Donald Trump and British Prime Minister Andy Burnham held their first in-person meeting at the U.N. General Assembly, where Trump praised the improved U.S.-U.K. relationship.
• Trump strongly opposed the United Kingdom's plan to transfer sovereignty of the Chagos Islands to Mauritius, calling the arrangement "terrible" and "ridiculous."
• U.S. opposition has stalled the legislation for the Chagos Islands transfer, despite Britain's intention to retain a 99-year lease on the strategically important Diego Garcia military base.
• The two nations announced a new partnership on artificial intelligence for critical infrastructure and defense technology, and successfully tested a U.S.-developed torpedo from a British uncrewed underwater vessel.
• Discussions also covered British sanctions on Israeli settlements, the war in Ukraine, trade, immigration, and the disputed Falkland Islands.

The renewed opposition from the U.S. President underscores significant diplomatic friction, potentially impacting the legal and operational stability of the strategically vital Diego Garcia military base.

British Prime Minister Andy Burnham and U.S. President Donald Trump held their inaugural in-person meeting on Tuesday at the United Nations General Assembly in New York. The encounter, which followed Burnham's arrival in the United States on Monday, September 21, 2026, accompanied by his wife Marie-France van Heel, was characterized by a notably positive tone from the American president. Trump remarked that the relationship between Washington and London had improved significantly under Burnham's leadership compared to that of his predecessor, Keir Starmer, describing it as "more up now" after a period he called "up and down."

President Trump further lauded Prime Minister Burnham as a "natural businessperson," revealing that the two leaders had engaged in several phone conversations prior to their face-to-face discussion. Burnham reciprocated the sentiment, acknowledging that they had "established a good connection in our early discussions" and had deepened that rapport during their meeting. This high-level engagement occurred just two months after Burnham assumed the prime ministership, succeeding Starmer.

In a demonstration of strengthened cooperation, Britain announced a new U.S.-U.K. partnership focused on artificial intelligence. This initiative aims to bolster critical infrastructure protection and advance defense technology. Further underscoring their collaborative efforts, the two nations successfully conducted a test firing of a U.S.-developed torpedo from a British uncrewed underwater vessel, highlighting tangible progress in defense capabilities.

Despite the cordial atmosphere and cooperative announcements, significant points of contention emerged, most notably concerning the Chagos Islands. President Trump unequivocally renewed his opposition to Britain's proposed transfer of sovereignty over the Chagos Islands to Mauritius. He condemned the arrangement as "terrible" and "ridiculous," stating, "I don't support it," and emphasized the strategic importance of the archipelago.

Last year, the United Kingdom had agreed to cede sovereignty of the Chagos Islands to Mauritius, while simultaneously planning to retain a 99-year lease on Diego Garcia. This island hosts a strategically vital U.S.-U.K. military base situated in the Indian Ocean. However, the legislative process for this transfer has been stalled due to persistent U.S. opposition. Prime Minister Burnham, speaking on Monday, reiterated his commitment to finding a resolution to this complex issue.

Other areas of discussion included Britain's decision to impose sanctions targeting trade with Israeli settlements in the occupied West Bank. While Trump deferred to Burnham on this matter, the Prime Minister defended the action, explaining that his administration had informed the U.S. of their rationale. Burnham argued that continued settlement construction risked undermining the viability of a two-state solution and that inaction would erode public trust. He also "completely" condemned the October 7, 2023, Hamas attacks, a stance Trump acknowledged as a "very strong condemnation." The leaders also touched upon Ukraine, trade, immigration, and the Falkland Islands, a disputed territory claimed by Argentina. Burnham welcomed Trump's earlier remarks regarding potential peace progress in Ukraine and affirmed Britain's readiness to contribute to Middle East stability.

The renewed opposition from the U.S. President underscores significant diplomatic friction, potentially impacting the legal and operational stability of the strategically vital Diego Garcia military base. The Chagos Islands, and specifically Diego Garcia, serve as a critical hub for U.S. and U.K. military operations in the Indian Ocean, making their sovereign status and lease arrangements a matter of profound geopolitical consequence. The U.S. stance complicates the United Kingdom's efforts to fulfill its commitment to Mauritius while maintaining its crucial defense alliance.

This ongoing dispute highlights the delicate balance the U.K. must strike between its international obligations and its strategic partnership with the United States. The legislative hold-up, directly attributable to U.S. concerns, signals that the transfer of sovereignty is far from a settled matter and remains a key point of contention in the U.S.-U.K. relationship. Earlier in the day, prior to his meeting with Trump, Prime Minister Burnham had also engaged with business leaders, including Apple executive chairman Tim Cook, at a New York roundtable, where he expressed his desire for a "single set of global pri" (the source text ends here).

This development signals significant US opposition to the UK's planned transfer of Chagos Islands sovereignty to Mauritius, potentially impacting the legal and operational stability of the Diego Garcia military base. Lawyers advising on international law, defense contracts, or geopolitical risk should monitor this ongoing diplomatic friction as it could affect future treaty negotiations and strategic asset management.
