White House admits Keir Starmer's relationship with Donald Trump is broken in attack on 'ungrateful' Britain

Mr Witkoff, one of Donald Trump's negotiating duo sent around the world for crunch talks with Vladimir Putin, Israel, Hamas and Iran, was probed on whether the PM had upset the special relationship.

"Sometimes we detect that there's not that feeling of gratitude," he said.

"The President's position is that we do plenty for Europe, plenty for the UK in trade, defence and the support we give to Nato.

"Sometimes the response back, the reciprocity... is a little bit lacking. I would leave it at that."

He also admitted the PM's relationship with Donald Trump was broken, telling GB News he hoped the duo could "repair" their "good, solid" rapport.

The special envoy's remarks add to more than a week's worth of stinging attacks on Sir Keir from the White House.

After the Prime Minister initially refused to allow US bombers to use UK bases, Mr Trump said he "was no Winston Churchill".

Sir Keir U-turned and let the Americans use British bases for "limited defensive operations" just hours later.

Then, insiders revealed to The Telegraph that the President had started referring to Sir Keir as a "loser who has no future" in private.

As war raged in the Middle East, Mr Trump revealed the UK was "giving serious thought" to sending ships to join US forces - but said this was too little, too late.

"We don't need people that join wars after we've already won," the President said.

The two leaders then butted heads in what is said to have been a frosty phone call days later.

Mr Trump was not interested in Sir Keir's explanation for stopping US planes using UK bases, a source familiar with the call told The i Paper.

They described it as a tense conversation - which also covered the King's upcoming State Visit to Washington DC for the States' 250th anniversary celebrations.

GB News understands officials have been considering scrapping or at least postponing the visit until the Iran conflict winds down.

After the contentious call, Nigel Farage travelled to Mr Trump's Mar-a-Lago base to meet the President's allies.

Mr Farage said he saw "very little prospect of the relationship between Trump and Starmer improving".

With HMS Dragon now on the way to Cyprus, Mr Witkoff again pointed to Mr Trump's criticism of Britain's speed to act.

"It does fall into the category of too little too late," he said.

However, the special envoy admitted: "We value support. We value alliances. The UK relationship with the United States is a critical one... I think they have a good, solid relationship and hopefully they'll be able to repair it."
