UK foreign secretary to meet Rubio as Diego Garcia tensions rise

UK–US Talks on Diego Garcia and Chagos Accord

Feb 20 (Reuters) - Britain's foreign minister Yvette Cooper will meet with U.S. Secretary of State Marco Rubio on Friday, after President Donald Trump renewed his criticism of London for ceding sovereignty of the Chagos Islands, which is home to a U.S.-UK air base.

Background on Chagos Sovereignty Deal

Last year British Prime Minister Keir Starmer agreed a deal to transfer sovereignty of the Indian Ocean islands to Mauritius, while keeping control of one - Diego Garcia - through a 99-year lease that preserved U.S. operations at the base.

Trump and Rubio's Diverging Signals

Washington last year gave its blessing to the agreement, but Trump has since changed his mind several times. In January, Trump described it as an act of "great stupidity", but earlier this month said he understood the deal was the best Starmer could make, before then renewing his criticism this week.

Implications for Iran Strategy

Cooper is meeting Rubio to discuss defence and security issues in Washington as Trump also toughens his rhetoric on Iran, saying Tehran must make a deal over its nuclear program in the next 10 to 15 days, or "really bad things" will happen.

Aid to Gaza and Houthi Operations

Operational Role of Diego Garcia

The Diego Garcia base has recently been used for operations in the Middle East against Yemen's Houthis and in humanitarian aid to Gaza.

Although on Tuesday Rubio's State Department said it backed the Chagos accord, the next day Trump said Britain was making a big mistake.

Trump's Truth Social Warning

"DO NOT GIVE AWAY DIEGO GARCIA!" Trump wrote in a post on Truth Social, saying the base could be called upon in any future military operation to "eradicate a potential attack" from Iran.

UK Approval Requirement for Base Use

Under the conditions for using the joint base, Britain would need to agree in advance to any operations out of Diego Garcia.

Media Report on Iran Strikes Permission

On Thursday, Britain's The Times newspaper reported that Trump's latest criticism of the Chagos deal came because Britain was yet to give permission to use the bases for future strikes against Iran, owing to concerns they may breach international law.

MOD Declines Operational Comment

Asked about The Times report, Britain's Ministry of Defence said on Thursday it does not comment on operational matters and that Britain supported the ongoing political process between the U.S. and Iran.
