Burnham and Trump forge rapport in New York, but Chagos deal remains a flashpoint
UK Prime Minister Andy Burnham and US President Donald Trump held their first face-to-face meeting at the UN General Assembly, where Trump praised Burnham as a 'natural businessperson' but criticized the UK's Chagos Islands deal as 'terrible.' Burnham expressed confidence in finding a resolution to the dispute over the Diego Garcia military base, while also affirming British sovereignty over the Falkland Islands in the face of US and Argentine tensions.
Key points
- Trump and Burnham met in New York, with Trump stating he can 'do business' with the UK leader and that UK-US relations have improved.
- Trump reiterated his opposition to the Chagos Islands deal, calling it 'terrible' and emphasizing the strategic importance of the Diego Garcia base for US operations.
- Burnham stated the UK will work to find a resolution for the Chagos deal, which was paused in April after Trump withdrew support, noting the UK will pay an average of £101m annually to lease the base.
- Burnham affirmed the UK's stance on the Falkland Islands, telling Trump that Britain will defend the islands' right to self-determination and remain British, countering US and Argentine claims.
- The leaders discussed artificial intelligence, with Burnham advocating for global standards and Trump rejecting any 'globalist scheme' to control AI, calling it 'super intelligence.'
Background
UK-US relations had previously strained under former Prime Minister Sir Keir Starmer, particularly after the UK refused to allow US bases for strikes on Iran. In August 2026, Trump dismissed a security scare involving a potential hoax message to Burnham, while also hinting at potential North Sea benefits for the UK. The Chagos deal, which involves ceding sovereignty to Mauritius and leasing back the Diego Garcia base, was paused indefinitely in April 2026 after Trump withdrew his support.
Why it matters
The outcome of the Chagos deal affects UK-US security cooperation and the future of a critical military base. Burnham's ability to navigate this dispute, along with tensions over the Falkland Islands and AI regulation, will shape the trajectory of UK-US relations and Britain's global security posture.
What to watch
Burnham and Trump will continue discussions on trade, immigration, and AI, with the UK aiming to resolve the Chagos deal and maintain the Diego Garcia base. The UK will also monitor US and Argentine actions regarding the Falkland Islands, while Burnham pushes for global AI standards despite US resistance.
