LONDON (Reuters) - U.S. President Donald Trump would take a “tougher” approach to Brexit negotiations than Britain’s Prime Minister Theresa May, he said in a television interview to be broadcast later on Sunday.

In the interview with British channel ITV, Trump said the European Union was “not cracked up to what it’s supposed to be” and claimed he had predicted the result of the June 2016 referendum in which Britons voted to leave the EU. Trump was elected to the U.S. presidency later the same year.

When asked if May was in a “good position” regarding the ongoing Brexit talks, Trump replied: “Would it be the way I negotiate? No, I wouldn’t negotiate it the way it’s [being] negotiated ... I would have had a different attitude.”

Pressed on how his approach would be different, he said: “I would have said the European Union is not cracked up to what it’s supposed to be. I would have taken a tougher stand in getting out.”

May was the first foreign leader to visit Trump after his inauguration in January last year and they were filmed emerging from the White House holding hands.

But the “special relationship” between the two nations has since faced several ups and downs, including Trump rebuking May on Twitter after she criticised him for retweeting British far-right anti-Islam videos.

He said in an earlier extract from the same interview that he had not intended to cause offence in Britain by sharing the videos and that he would apologise if the original posters were horrible racists.

Trump’s comments on militant attacks in Britain have angered some and he has often exchanged barbs on social media with London Mayor Sadiq Khan.

Trump also said in the interview that he had anticipated the Brexit referendum result because of many Britons’ concerns over immigration -- also a key plank of his U.S. election campaign.

“I said [that] because of trade, but mostly immigration, Brexit is going to be a big upset. And I was right,” he said. “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.”

Trump also said he had been invited by May to make two visits to Britain this year.

Earlier this month, he cancelled a trip to London to open a new embassy, saying he did not want to endorse a bad deal agreed by the Obama administration to sell the old one for “peanuts”.

Some Britons are angry at the prospect of a visit by Trump, with large protests expected when he does arrive.

Asked in the interview if he had been invited to the wedding of Britain’s Prince Harry and his American fiancée Meghan Markle, Trump said: “Not that I know of.”

He declined to say if he would like to attend the wedding at Windsor Castle but added: “I want them to be happy. I really want them to be happy.

“They look like a lovely couple.”
