DONALD Trump cancelled his trip to London because he’s “not been shown enough love” by the British government, according to a source close to the US president.

Downing Street officials were said to have been at an “advanced stage” of planning the visit to the UK by the US President when he abruptly let it be known on Thursday that he would no longer be coming, as expected, to open the new American embassy.

He blamed it on a “bad deal” involving the sale of the previous embassy building in Grosvenor Square, Mayfair, and the purchase of a new site at Nine Elms on the south bank of the Thames.

The Sunday Times’s source said Trump’s distaste for what he described as the “off location” of the new embassy was “just an excuse” to cancel the visit, which had been pencilled in for February 26 and 27.

“He felt he had not been shown enough love by the British government,” the source added. “He started to believe that the British government thought the same way about him as Sadiq Khan and Jeremy Corbyn, who have made clear their disdain for him and said he is not welcome in the UK.”

Trump’s visit would likely have led to some of the biggest protests in London since the war in Iraq.

Tory politicians, who have put their faith in Trump and America to give the UK a generous post-Brexit trade deal, have put the blame for the White House cancelling firmly on Labour, with Boris Johnson calling Khan a “popinjay”.

Sir Nigel Sheinwald, who served in Washington from 2007-12, told The Observer that after Trump’s latest outburst the UK “should put out of our minds the idea that just around the corner when we leave the EU there is a magical deal with the US that is going to solve all our trade and industrial problems”.

He added: “If you’re a Liam Fox, who has staked so much on the American deal being easy and within our reach around the same time as Brexit, then the way in which the bilateral relationship has atrophied and the tone has changed in the last year since May’s first visit is quite a big blow.”

The new £730m US embassy opens to the public tomorrow.

Trump’s mental health is also in question, despite White House physician, Dr Ronny Jackson, claiming the President was in excellent health following his medical on Friday.

A group of high profile physicians recently wrote to Jackson asking them to test the president for signs of dementia.

The White House recently dismissed questions about Trump’s mental fitness made in Michael Wolff book Fire and Fury, calling them “disgraceful and laughable.”

Citing people close to the President, Wolff has said the President has begun repeating three stories in conversations in less than 10 minutes, when he used to repeat stories in about a 30-minute window. Wolff told CNN that “100 per cent of the people around the President believes he’s incapable of carrying out the duties of office.”

Trump and the White House have ridiculed Wolff and his book, calling it fiction.

“Actually, throughout my life, my two greatest assets have been mental stability and being, like, really smart,” Trump said on Twitter earlier this week, before describing himself as a “very stable genius.”

It comes as another leak from the White House, possibly, inadvertently from the President himself, suggests Trump has defended describing Haiti and African countries as “shitholes”.

Speaking privately to friends and outside advisers, he apparently said he was only expressing what many people think.

One person he spoke to by phone, said Trump denied he was racist, and blamed the media.
