The US President said he was hopeful of securing a “great” trade deal with the UK when it leaves the bloc but appeared to question the stance Mrs May had taken over Brexit.
After appearing to patch-up his differences with the Prime Minister at Davos this week, the US President has risked causing a further diplomatic row by weighing in on the subject.
In an interview, to be broadcast on ITV this evening, Donald Trump was asked if he thought the Government was in a “good position” as talks move on to trade.
He replied: “Would it be the way I negotiate?

“No, I wouldn’t negotiate it the way it’s negotiated. I would have had a different attitude.”
He then went on to attack the EU, saying he had “a lot of problems” in trade discussion with the bloc and caused it of being “unfair”.
Mr Trump said: “I would have said that the European Union is not cracked up to what it’s supposed to be.
“I would have taken a tougher stand in getting out.
Donald Trump blasted the EU
“You know, I have a lot of problems with the European Union. I’m representing the United States, it’s a very unfair situation. We cannot get our product in. It’s very, very tough.
“And yet they send their product to us – no taxes, very little taxes. It’s very unfair.
“I’ve had a lot of problems with European Union, and it may morph into something very big from that standpoint, from a trade standpoint.
“The European Union has treated the United States very unfairly when it comes to trade.
“They’re not the only one, by the way. I could name many countries and places that do.
“But the European Union has been very, very unfair to the United States. And I think it will turn out to be very much to their detriment.”
Mr Trump said he understood why Britain had decided to leave the EU and it had been the right decision.
He told Mr Morgan: “I said because of trade, but mostly immigration, Brexit is going to be a big upset. And I was right.

“I know the British people and understand them.
“They don’t want people coming from all over the world into Britain, they don’t know anything about these people.”
The President vowed to make a “great” trade deal with the UK, but only after the “tough” two-year transition period.
He said: “As you know, you’re somewhat restricted because of Brexit.
“You have a two-year restriction. And when that restriction is up, we’re going to be your great trading partner. It’s a tough restriction to have.
Mr Trump said he would take a tougher line on Brexit
“You know, for a couple of years, you have a very strong lack of being able to do things.”
Mr Trump’s comments on Brexit comes at a time when Mrs May is facing huge pressure from backbenchers who fear she is backsliding on her commitment to a clear break.
Ex-Cabinet minister Theresa Villiers is the latest Brexiteer to fire a broadside against the PM, warning Britain is heading towards a “dilution of Brexit”.
She said: “Since the Prime Minister set out a bold vision in her Lancaster House speech, the direction of travel seems to have gone in only one single direction: towards a dilution of Brexit.
Jacob Rees-Mogg has also criticised the PM’s approach
“If the Government goes too much further down that path, there is a real danger that it will sign up to an agreement which could keep us in the EU in all but name and which would therefore fail to respect the referendum result.”
Chancellor Philip Hammond was criticised this week for saying the UK’s trade relations with the EU would change only “very modestly” after Brexit, sparking anxiety among Leavers that Brexit may be delivered “in name only”.
Mr Hammond was rebuked by Number 10 but stoked Tory divisions further by saying the UK should seek a “middle way” in negotiations in order to maximise access to EU markets.
Ms Villiers is the latest senior Conservative to voice concerns about the direction of negotiations, with leading Brexiteer Jacob Rees-Mogg warning Theresa May earlier this week that if she delivers “Brexit in name only” with a status quo transition period, the Conservatives will lose the next election.
