Trump's Chagos broadside leaves Starmer walking an even thinner tightrope

Donald Trump detonated a series of bombshells on his Truth Social overnight.

There was the leaking of private messages from France's President Emmanuel Macron, the posting of images of Canada and Greenland as part of the US, and then going all out on Sir Keir Starmer and the UK by calling the Chagos deal an "act of great stupidity" - opening him up to attacks from opposition MPs long-opposed to the deal. I've been speaking around government to get a sense of what the hell is going on after the prime minister sought to reiterate the UK's position on Greenland on Monday while also trying to de-escalate, stressing the strong relationship, dodging the matter of retaliatory tariffs (although not ruling it out) and avoiding any incendiary language adopted by other leaders clearly fed up with Trump.

But what is also clear is that the UK government is not going to change its position on Greenland, nor is it going to wobble on Chagos, and will press on with the agreement with Mauritius.

The lashing out against the UK and Starmer seems to be part of a bigger assault on allies - as Trump reveals private messages with Macron and shares a map of Canada as US territory, which will no doubt explode in Canada. This is what Work and Pensions Secretary Pat McFadden said: "What we saw last night...

was a series of posts criticising a number of world leaders. That may tell us that the president is frustrated right now.

"I don't really believe this is about Chagos. I think it's about Greenland and the best way to resolve that is through dialogue with the Danish government and that's what we've said all along." Trump is clearly frustrated that European allies are standing firm on Greenland and facing down his threats, regardless of the consequences of the tariffs.

Meanwhile, his Board of Peace plan has also fallen flat as he demands $1bn (£744m) for membership of a club that seems intended to undermine the United Nations. France intends to reject Trump's invitation over concerns that it would call into question "the principles and structure of the United Nations.
