DONALD TRUMP has warned that he may not have a “very good relationship” with David Cameron if he is becomes the next US president.
The billionaire Republican candidate was responding to comments the prime minister made last year after Mr Trump’s proposal to ban Muslims from entering the US.
The presidential hopeful also sniped at new London Mayor Sadiq Khan, calling him "ignorant" for comments he made after being elected, and warned him: "I will remember those statements."
The Republican nominee, who is likely to go against Democrat Hillary Clinton in a bid for the White House in November, was speaking to Piers Morgan on ITV's Good Morning Britain.
Mr Cameron has refused to retract comments he made about the billionaire tycoon's Muslim ban comments, that he branded "divisive, stupid and wrong".
Mr Trump dismissed the remarks, but issued a rebuke to the prime minister saying: "It looks like we are not going to have a very good relationship.
“Who knows, I hope to have a good relationship with him but he's not willing to address the problem either." Mr Trump said he was "not stupid" and denied he was divisive.
He went: "I'm a unifier, unlike our president now, I'm a unifier."
On being elected London Mayor, Mr Khan blasted Mr Trump as "ignorant" in his views on Islam and he risked harming security on both sides of the Atlantic.
Mr Trump said: "He doesn't know me, hasn't met me, doesn't know what I'm all about. I think they were very rude statements and, frankly, tell him I will remember those statements. “They are very nasty statements."
He added: "When he won I wished him well. Now, I don't care about him, I mean, it doesn't make any difference to me, let's see how he does, let's see if he's a good mayor."
Mr Trump said he was offended by Mr Khan's public denouncement but denied he was "at war" with him.
Speaking after his election, the mayor said his "ignorant view of Islam could make both of our countries less safe — it risks alienating mainstream Muslims around the world and plays into the hands of extremists".
Mr Trump said: "I just think it's very rude of him. In fact it's the opposite. I wished him well when I heard he won, he's a Muslim, I think it's ignorant for him to say that."
The businessman turned politicians also waded into the EU referendum debate, saying he thinks Brussels has been a “disaster” and “is very difficult”.
He added: “If I were from Britain, I would probably not want [the EU].”
He appeared to partially alter his call for a temporary ban on Muslims entering the US after the new London mayor was sworn in, saying there would be "exceptions".
The presidential hopeful said the policies he mooted on the campaign trail were just "suggestions", but said there was a "tremendous" problem with Islamic extremism.
He said: "It's not Sweden doing the damage — we have a real problem and we have to discuss it."
When pressed over whether Britan would be at the back of the queue with regards to a trade deal with the US, as threatened by Barack Obama last month, he rejected the notion entirely.
He said: “You have to make your own deal. Britain’s been a great ally. With me, they’ll always be treated fantastically.
“You would certainly won't be back of the queue, that I can tell you.”
