Donald Trump has said he may struggle to work with David Cameron if he wins the White House race – because the Prime Minister criticised his views as ‘divisive, stupid and wrong’.

The presumptive Republican presidential nominee said: ‘Looks like we’re not going to have a very good relationship.’

In December, the Prime Minister hit out at Mr Trump after he called for a ban on Muslims entering the US and claimed police in London ‘fear for their lives’ because some communities are so radicalised.

Donald Trump today said he would not send Britain to the 'back of the queue' for a trade deal with the US if he wins the White House in November

Since then, the billionaire has all but clinched the battle to become the Republican nominee, with polls suggesting the November election may be a tight race between him and his Democrat opponent, likely to be Hillary Clinton. Earlier this month Mr Cameron said he had ‘no intention of withdrawing’ the comments.

Yesterday Mr Trump told Piers Morgan, in an interview to be shown in full on ITV today: ‘Looks like we’re not going to have a very good relationship.

‘Who knows: I hope to have a good relationship with him. But it looks like he’s not willing to address the problem either.

‘Number one: I’m not stupid... just the opposite. And number two I don’t think I’m a divisive person, I’m a unifier.’

Mr Cameron’s initial criticism of Mr Trump came in the Commons after the tycoon said he would temporarily ban all Muslims from entering the US if he became president. The Prime Minister said: ‘I think his remarks are divisive, stupid and wrong. If he came to visit our country I think he would unite us all against him.’

The comments were made when it seemed unlikely Mr Trump would win the nomination. But two weeks ago Mr Cameron refused to apologise.

While declaring that anyone who makes it through the gruelling US presidential primaries deserves respect, he added: ‘But what I said about Muslims, I won’t change that view. I am very clear that the policy idea put forward was wrong, is wrong and will remain wrong.’

In the same Piers Morgan interview Mr Trump said a post-Brexit UK would not be sent to the back of the queue to secure a trade deal with the US should he become president.

His comments contradict those of President Barack Obama who on a visit to Downing Street warned last month that Britain would be ‘at the back of the queue’ in terms of a trade deal. Mr Trump repeated his opinion that the UK should leave the EU and said: ‘I think if I were from Britain I would probably want to go back to a different system.’

Asked if the UK would be at the front of the queue for a trade deal under a Trump presidency, he replied: ‘I don’t want to say front or anything else. I mean, I’m going to treat everybody fairly but it wouldn’t make any difference to me whether they were in the EU or not.’

He added: ‘You’d certainly not be back of the queue, that I can tell you.’

Tory former deputy prime minister Lord Heseltine, 83, said Mr Trump had joined Russian president Vladimir Putin in supporting Brexit and both were ‘playing with fire’. He said he believed Britain might struggle to survive alone outside the EU.

Ukip leader Nigel Farage, responding to the clip aired on ITV's Peston On Sunday, joked: 'It just goes to show Donald Trump is measured, neutral, doesn't want to get stuck into the punch-up.'

Mr Farage added: 'He's given a very diplomatic answer.'

The Euro MP said investors believe it makes no difference whether Britain chooses to stay or leave the EU.

Asked if he would back Mr Trump for US president, Mr Farage said: 'I have difficulty with that.

'Let's put it like this, I couldn't vote for (Hillary Clinton) even if you paid me.'

He added: 'If you put me up against a wall it would be (Mr Trump), not Hillary, but I have reservations.

'Encouraging people to beat up protesters, one or two things like that bother me, but look, I tell you what, I think he's going to win.'

David Cameron has repeatedly refused to apologise to Mr Trump after declaring him to be 'divisive, stupid and wrong'.
