Mauritian politician, current prime minister since 2024
Britain’s new prime minister has arrived in New York for the UN General Assembly, seeking closer UK-US ties on Ukraine air defences and safeguarding shipping routes, while navigating a fraught relationship with President Trump. Officials warn of economic headwinds as winter looms.
Britain has reached a deal with Mauritius to cede sovereignty over the Chagos Islands, while maintaining a 99-year lease on Diego Garcia and its strategic base. The agreement has yet to gain legal force as the US expressed concerns and opposition from Washington has slowed parliamentary passage.
The UK and US leaders have met on the sidelines of the UN General Assembly. They have praised their connection, but remain divided over the Chagos Islands deal and the push for global AI safety standards. Burnham has emphasised long-term cooperation on security and AI, while Trump continues to press his Iran stance and criticises the deal.
Pacific nations and allies press for urgent action on climate finance, ocean health, and keeping 1.5°C within reach ahead of COP31 in Turkey. Pre-COP meetings in Fiji and Tuvalu highlight vulnerability to sea-level rise and demand concrete, community-level finance and adaptation.
