Donald Trump has given an exclusive 30 minute chat with Piers Morgan on board Air Force One before the president flew to Scotland this evening.

The interview will air on Good Morning Britain on ITV on Monday morning.

The TV host tweeted: "I’ve been on a few fancy planes in my time but nothing quite like this one."

Air Force One was held on the tarmac at Stansted Airport for 30 minutes for the conversation between the two.

The interview is thought to be an exclusive for ITV and comes less than a day after Trump disparaged May's Brexit negotiating to The Sun.

In that incendiary interview the American commander-in-chief also said Boris Johnson would be a 'good Prime Minister' and blamed London mayor Sadiq Khan for not tackling terrorism in the capital.

The US president, alongside his wife Melania, enjoyed afternoon tea with the Queen at Windsor Castle before flying off to Scotland where he will spend two nights.

Before the flight took off Trump took part in an interview with Good Morning Britain presenter - and Trump fan - Piers Morgan aboard Air Force One.

It is widely thought Trump will play golf at one of his courses between now and his flight to Helsinki - to meet with Russian President Putin - on Sunday.

Meanwhile organisers claimed 250,000 protesters lined the streets of London to register their disdain for the 45th president. That figure has not been verified.

At an explosive press conference at Chequers this afternoon Trump continued to say Brexiteer Boris Johnson would make a good Prime Minister but also backed Theresa May's leadership.

Trump, who falsely claimed he 'predicted ' Brexit the day before the vote in June 2016, said “As far negotiating the deal I probably would have done what my suggestion was to the Prime Minister, but she can always do that. She can do what I suggested to her.

Asked if that meant walking away, he said: “Well, you can’t walk away, because if she walks away that means she’s stuck. You can’t walk away.

“But you can do other things. She can do what my suggestion was. And my suggestion was respectfully submitted.”

The President also said he had apologised to Mrs May this morning for The Sun interview in which he had suggested a US trade deal wouldn’t be possible under her Brexit plan

But he claimed the Prime Minister had responded: “Don’t worry, it’s only the press.”
