In an interview on the Andrew Marr Show on BBC TV on Sunday, the Prime Minister revealed Donald Trump had advised her to take legal action against the European Union during the Brexit negotiations. "Actually, no, we're going into negotiations with them".
Tory Brexiteer Jacob Rees-Mogg has issued a fresh warning to May to change tack on her blueprint for leaving the European Union - or see her party split.
Mrs May laughed off the president's legal action suggestion, saying she would carry on with negotiations, but added: "Interestingly, what the president also said at that press conference was "don't walk away". He added: "If they don't make the right deal, she might very well do what I suggested".
As more than 250,000 people took to the streets of London and other United Kingdom cities on Friday in protest of U.S. President Donald Trump and his policies, the leader told a baffled Piers Morgan that "many, many" of the demonstrations were actually pro-Trump.
He also praised Mrs May's rival, Boris Johnson, who quit last week as foreign secretary to protest her Brexit plans. "In fact, I told Theresa May what I thought she should do and she disagreed", he said.
The size of the threat should become clear on Monday when lawmakers vote on amendments to legislation on the government's post-Brexit customs regime, with leading eurosceptics set to vote in favor of amendments that May opposes and back their own proposals to toughen up her exit plan.
May's Brexit blueprint calls for a new UK-EU "free trade area" with interlinked customs regimes, but critics argue that it would leave Britain signed up to rules on trade it would no longer have any ability to influence and prevent it from signing trade deals with non-EU countries.
As always, sensible advice from the Leader of the Free World..
The video has not only left the British offended, it has led to many calling him a "narcissist". "She wanted to go a different route", he said.
In this Friday, July 13, 2018 photo, a Greenpeace protester flying a microlight passes over US President's Donald Trump's resort in Turnberry, Scotland. But the exchange was the latest example of the awkward dance between the US and Britain, with the two leaders attempting to put on a public show of friendliness despite clear strains over trade, the European Union and their approaches to diplomacy.
In an article for The Mail on Sunday, Theresa May warns rebels on both sides of her party that there is no other "workable alternative future trading relationship" to the plan agreed at Chequers, and fleshed out in a white paper this week.
Mrs May denied that Mr Davis, the former Brexit secretary, had been "cut out" of the plan and therefore had no choice but to resign.
'My job as Prime Minister is to deliver for them, but also I've got to be hard-headed and practical about this and do it in a way that ensures we get the best interests for the United Kingdom'. "I gave her a suggestion, not advice".
After meeting with May on Friday, however, Trump seemed to roll back his comments, declaring a deal would be "absolutely possible".
