UK rejects US plan to use bases for Iran strike as Trump weighs military options

The United Kingdom has reportedly blocked a U.S. request to use British-controlled bases for a potential strike on Iran, according to British media reports.
The decision by Prime Minister Keir Starmer, first reported by The Times, was said to be driven by concerns that such action could breach international law. U.S. President Donald Trump had sought access to facilities at Diego Garcia in the Indian Ocean and RAF Fairford in Gloucestershire, a key hub for America’s heavy bomber fleet.
The development comes amid escalating U.S. pressure on Iran over its nuclear programme. Trump has warned of “unfortunate” consequences if ongoing negotiations fail and has indicated he is considering military options. According to reports, he issued a 10-day ultimatum to Tehran and later suggested a possible “10 to 15 days” window for a deal.
American journalist and former intelligence officer John Kiriakou, citing White House sources, claimed Trump had decided on a potential strike early next week. He also alleged divisions within the administration, with Vice President JD Vance and Tulsi Gabbard reportedly opposing military action, while Secretary of State Marco Rubio, Defense Secretary Pete Hegseth and senior military officials were said to be supportive.
The New York Times reported that Washington is weighing various strike options. The U.S.S. Gerald R. Ford aircraft carrier and accompanying vessels were recently deployed to the Middle East, joining other warships near Iran, expanding military readiness in the region.
Trump also posted on Truth Social that use of Diego Garcia and Fairford might become necessary if Iran refuses a deal.
According to The Times, Starmer’s refusal has also factored into renewed U.S. criticism of the U.K.’s agreement to transfer sovereignty of the Chagos Islands to Mauritius while retaining a 99-year lease on Diego Garcia.
