US president Donald Trump has launched a blistering attack on Britain, calling Sir Keir Starmer’s plan to cede the Chagos Islands to Mauritius one of “great stupidity”.
Writing on his Truth Social platform, the US president said the deal is “another in a very long line of National Security reasons why Greenland has to be acquired”.
The criticism comes just one day after the UK prime minister called for calm amongst the US and Nato allies, amid rising tensions over Trump’s Greenland ambitions.
The US president wrote in an online rant: “Shockingly, our “brilliant” NATO Ally, the United Kingdom, is currently planning to give away the Island of Diego Garcia, the site of a vital U.S. Military Base, to Mauritius, and to do so FOR NO REASON WHATSOEVER.”

Last year, the Sir Keir agreed a controversial deal to hand over the Chagos Islands to Mauritius, while retaining control of the UK-US military base on Diego Garcia.
The UK has agreed to pay Mauritius at least £120 million annually during the 99-year agreement to lease back the site, a total cost in cash terms of at least £13 billion.
In February last year, Trump appeared to indicate his support for the deal as he told Sir Keir during his visit to the White House in February that he was “inclined to go with your country” and that he had “a feeling it’s going to work out very well”.
But early on Monday morning, the US president launched a scathing attack on the move, linking it to his ambitions to control Greenland.
“There is no doubt that China and Russia have noticed this act of total weakness,” he wrote.
“These are International Powers who only recognize STRENGTH, which is why the United States of America, under my leadership, is now, after only one year, respected like never before.
“The UK giving away extremely important land is an act of GREAT STUPIDITY, and is another in a very long line of National Security reasons why Greenland has to be acquired. Denmark and its European Allies have to DO THE RIGHT THING.”
