The US president described Britain as “our once great ally” as he told the prime minister that America doesn’t need the two Royal Navy aircraft carriers due to be sent to the Gulf.

He added: “We will remember. We don’t need people that join Wars after we’ve already won.”

Trump’s comments, in a post on Truth Social, are another shattering blow to the so-called “special relationship” between Britain and America.

The president said: “The United Kingdom, our once Great Ally, maybe the Greatest of them all, is finally giving serious thought to sending two aircraft carriers to the Middle East. That’s OK, Prime Minister Starmer, we don’t need them any longer — But we will remember. We don’t need people that join Wars after we’ve already won!”

Trump has been furious with Starmer ever since he turned down his initial request for US jets to use British bases to launch bombing raids alongside the Israelis in Iran.

Starmer changed his mind las Sunday after Iran began bombing countries across the Gulf region, putting up to 300,000 British lives at risk.
