The UK has reportedly refused to authorize the use of its airbases specifically Diego Garcia and RAF Fairford for potential U.S. strikes against Iran.

The United Kingdom has refused to authorize the use of its Royal Air Force bases including Diego Garcia in the Indian Ocean and RAF Fairford for potential U.S. strikes against Iran, citing concerns related to international law.

Reports indicate that this dispute became the reason President Trump withdrew support for the UK’s agreement with Mauritius regarding the transfer of the Chagos Islands. While the U.S. is preparing strike plans, British consent is required — and has not been granted so far.

Trump reportedly suspended backing for London’s Chagos deal after the UK declined to approve the use of Diego Garcia and Fairford for operations against Iran. Under existing agreements, U.S. military operations from these bases require British authorization, which was withheld on legal grounds. Officials state that the Chagos arrangement cannot proceed without U.S. support.
