DONALD TRUMP was still an hour from landing in Stansted on his first official trip to Britain, when he managed to humiliate Theresa May.

The President, who has close ties to Nigel Farage, berated the Prime Minister’s Brexit plan, agreed last week in Chequers, and despised by Brexiteers.

Speaking to reporters in Brussels, in a surprise press-conference at the end of the two-day Nato summit, Trump said he didn’t think the Tory leader’s proposals were what the people had voted for when they backed Leave in the referendum.

With a smirk, he told journalists that the UK was a “hot spot right now with a lot of resignations”.

“I would say Brexit is Brexit,” he said. “The people voted to break it up so I would imagine that’s what they would do, but maybe they’re taking a different route – I don’t know if that is what they voted for.”

He added that the UK seemed to be “getting at least partially involved back with the European Union”. “I’d like to see them be able to work it out so it could go quickly,” he said.

It wasn’t even the first time this week Trump has embarrassed May.

Just days ago he told reporters on the White House lawn that he had “always liked” Boris Johnson, who quit as foreign secretary over the Chequers agreement, and said he might even find time to meet him while in the UK.

The unpredictable, human-hand-grenade arrived in Britain after causing carnage in Brussels. His hosts in London were almost certainly preparing for similar fallout here, but May has staked a lot on the her relationship with the President.

The Prime Minister hosted Trump and the First Lady at Blenheim Palace at a dinner for 150 business people, politicians, and prominent Americans.

The country estate, which is the family seat of Jamie Blandford, the Duke of Marlborough, who has more than 20 convictions going back 30 years for drug offences, burglary, criminal damage, numerous driving offences and even punching a police officer, was chosen partly for its lavishness, party for its history – it’s the birthplace of Winston Churchill – and partly because it’s not in the centre of London.

That, however, didn’t deter protesters.

After spending the night at the US ambassador’s official residence in Regent’s Park, London, Trump and May will today observe a joint counter-terrorism exercise involving UK and US special forces.

The two leaders will then hold talks at Chequers, discussing Nato, Brexit and the Middle East. They’ll also almost certainly be talking about Russia and Vladimir Putin, who Trump is due to meet on Monday at a summit in Helsinki.

Later Trump will travel to Windsor Castle, where he’ll have an audience with the Queen.

The president and his wife will then head to Scotland, with Air Force One due to land in Prestwick this evening.

A motorcade and the presidential limo, known as the Beast, were flown into Ayrshire on Wednesday.

Trump’s son Eric has arrived in Scotland for a golfing visit to Trump International Golf Links at Menie, Aberdeenshire, and Trump Turnberry, near Girvan, South Ayrshire.

The Scottish Government confirmed yesterday that neither Nicola Sturgeon or any of her ministers would be meeting with the president during his trip to Scotland.

A Scottish Government spokesperson said: “President Trump is coming to the UK at the invitation of the UK Government and the Secretary of State for Scotland will greet him on arrival. We understand the president’s time in Scotland is planned as a personal private visit between other engagements with no official meetings. The Scottish Government has been planning for this for some time with key partners, including Police Scotland, and we will continue to work with them as required on the final preparations.”

David Mundell, who will meet the President off the plane, said he wanted to “emphasise” the close links between Scotland and America.

“I think it’s very important to recognise that this is a visit by the President of the United States, the head of the United States and it’s in that capacity that we do welcome him to Scotland.

“He’s already himself invested significantly in Scotland. I hope that he does have a good time here while he is golfing at his Turnberry resort.”

Other Scottish politicians were less enthusiastic.

Scottish Labour’s Richard Leonard will be addressing the protest in Glasgow’s George Square tonight. He said it was important the right message was sent out as the eyes of the world would be on Scotland.

“We are clear in our view that Donald Trump’s visit does not have the consent of the people, that we stand for freedom of speech and we stand for hope and common humanity.”
