Donald Trump has mocked Keir Starmer over the UK’s response to the US-Israeli bombing of Iran.

The American president said “this is not Winston Churchill that we’re dealing with” after Starmer initially refused to let the US use British bases to launch their attacks amid concerns the strikes broke international law.

The PM eventually changed his mind after Iran began bombing countries across the Middle East, putting British lives at risk.

Trump’s Oval Office comments mark a new low in the so-called “special relationship” between America and the United Kingdom.

Referring to the UK military base at Diego Garcia, he said: “That island… It’s taken three, four days for us to work out where we can land there, it would have been much more convenient landing there as opposed to flying many extra hours, so we are very surprised.

“This is not Winston Churchill that we’re dealing with.”

Trump’s comments are just latest criticism he has aimed at Starmer since America and Israel’s attacks on Iran began at the weekend.

In an interview with the Telegraph on Monday, the president said he was “very disappointed” in the PM.

That prompted Starmer to hit back in the Commons, telling MPs: “President Trump has expressed his disagreement with our decision not to get involved in the initial strikes.

“But it is my duty to judge what is in Britain’s national interest. That is what I’ve done, and I stand by it.”

In another dig at the US president, Starmer said: “This government does not believe in regime change from the skies.”

Trump responded in an interview with The Sun in which he said the PM “has not been helpful”.

“I never thought I’d see that,” he said. “I never thought I’d see that from the UK. We love the UK.”

He added: “It’s not going to matter, but [Starmer] should have helped… he should have.

“I mean, France has been great. They’ve all been great. The UK has been much different from others.”

Trump continued: “You’ve seen the secretary general of NATO, the great things he said, Mark Rutte, he’s great.

“No, they’ve all been pretty much great other than…we think Keir’s was just very different.”

The president said the spat over Iran meant “it’s just a much different kind of relationship that we’ve had with your country before”.
