Britain’s Foreign Minister Yvette Cooper is scheduled to sit down with U.S. Secretary of State Marco Rubio this Friday, as tensions escalate following President Trump’s repeated attacks on London’s decision regarding the Chagos Islands sovereignty deal.
The controversy centers around an agreement reached last year by British Prime Minister Keir Starmer to hand over sovereignty of the Indian Ocean island chain to Mauritius. However, Britain retained control of Diego Garcia through a 99-year lease arrangement that allows continued U.S. military operations at the strategic air base.
While the Washington administration initially supported the arrangement last year, Trump has since flip-flopped on the issue multiple times. The president called the decision an act of “great stupidity” in January, then seemed to soften his stance earlier this month by saying he understood it was the best deal Starmer could negotiate, only to resume his attacks this week.
Cooper’s Washington meeting with Rubio will focus on defense and security matters, coming at a time when Trump is also escalating pressure on Iran, demanding Tehran reach a nuclear agreement within 10 to 15 days or face consequences he described as “really bad things.”
The Diego Garcia facility has played a crucial role in recent Middle East operations, including missions against Yemen’s Houthis and humanitarian assistance efforts to Gaza.
Despite Rubio’s State Department expressing support for the Chagos agreement on Tuesday, Trump reversed course the following day, declaring Britain was making a serious error.
“DO NOT GIVE AWAY DIEGO GARCIA!” Trump posted on Truth Social, emphasizing the base’s importance for potential future military actions to “eradicate a potential attack” from Iran.
The current arrangement requires Britain’s advance approval for any operations launched from Diego Garcia, a condition that may be complicating U.S. military planning.
According to a Thursday report in Britain’s The Times, Trump’s renewed criticism stems from Britain’s reluctance to authorize the base for potential Iranian strikes due to concerns about violating international law.
When questioned about The Times’ reporting, Britain’s Ministry of Defence declined to discuss operational details Thursday, stating only that Britain supports ongoing diplomatic efforts between the United States and Iran.
