“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,” he told MPs.

Trump told journalists in the Oval Office earlier this week he was “not happy with the UK” over the initial decision to refuse use of UK bases, which led to US planes “flying many extra hours” to carry out strikes last weekend. He also told reporters Sir Keir is “no Winston Churchill”.

Sir Keir has insisted the “special relationship” between the US and the UK had not been fractured while speaking to reporters on Thursday.

“Look, the special relationship is in operation right now,” he said. “We’re sharing intelligence on a 24/7 basis in the usual way. That is the special relationship.”

On Friday, a US B-1 bomber was seen landing at RAF Fairford, in Gloucestershire.

For many months Sir Keir has pointed to his relationship with Trump as one of the biggest successes of his premiership.

That is no longer the case. This is just the latest example of President Trump being openly critical towards the prime minister, and it is clear he is still angry the UK blocked him from using British bases when he first launched strikes against Iran.
