(Alliance News) - UK Foreign Secretary Yvette Cooper will meet her US counterpart Marco Rubio for talks in Washington after Britain's Chagos Islands deal was thrown into fresh doubt by Donald Trump.
The UK's agreement to hand sovereignty of the British Indian Ocean Territory to Mauritius, a move repeatedly criticised by the US president, is likely to be high on the agenda.
Earlier this week, Trump urged UK Prime Minister Keir Starmer not to "give away Diego Garcia" – an island on the archipelago which is home to a joint UK-US military base – despite Washington signalling its official backing for the deal on Tuesday.
Trump's latest U-turn on his previous support for the agreement is because of Britain's refusal to give the White House the green light to use the base or RAF Fairford in Gloucestershire for a potential military campaign against Iran, according to the Times.
The government's position is said to be due to concerns over a breach of international law, which does not distinguish between a nation carrying out an attack and one that provides support with "knowledge of the circumstances of the internationally wrongful act".
The bases can only be used for military operations with prior consent from the government and would need to comply with UK law and the country's interpretation of relevant international law.
The US president is weighing fresh military action against the Islamic Republic, with a second American warship moving into the region and warnings that he could go ahead if no deal on its nuclear programme is reached.
In a post on his Truth Social platform, Trump said that "it may be necessary" for the US to use Diego Garcia "and the airfield located in Fairford" in order to "eradicate a potential attack by a highly unstable and dangerous regime".
A government spokesperson refused to comment on "operational matters" and said there was a political process "ongoing between the US and Iran, which the UK supports".
"Iran must never be able to develop a nuclear weapon, and our priority is security in the region," they said.
Foreign Secretary Cooper and US Secretary of State Rubio are expected to hold talks on UK-US cooperation on a range of areas including defence, security and trade.
The minister will also attend the National Governors' Association Reception, where she will meet with a range of US governors and discuss business opportunities for British firms as well as celebrating the 250th anniversary of American independence.
