President Trump on Thursday blamed Prime Minister Theresa May for the UK's Brexit disaster, saying she disregarded his recommendation on arranging her country's takeoff from the European Union and exacerbated the situation.

“I would have done it much differently,” Trump told The Sun newspaper in an explosive interview just hours before rubbing elbows with the British leader at a lavish black-tie dinner at Blenheim Castle in Oxfordshire.

“I actually told Theresa May how to do it but she didn’t agree,” he said. “She didn’t listen to me. She wanted to go a different route. I would actually say that she probably went the opposite way. And that is fine. She should negotiate the best way she knows how. But it is too bad what is going on.”

The president went ahead to state May's arranging strategies may have destroyed any possibility of hitting an exchange agreement with the United States.

"In the event that they complete an arrangement like that, we would manage the European Union as opposed to managing the UK, so it will most likely execute the arrangement," the president said.

"On the off chance that they do that, at that point their exchange manage the US will presumably not be made."

Portions from the stunner meet were distributed Thursday similarly as Trump was planned to eat with May at the castle.

While the president said he preferred May and thought of her as a "decent individual," he hurled fuel on officially seething pressures over how the UK will haul out of the EU one year from now.

"The arrangement she is striking is a much ­different bargain than the one the general population voted on," Trump said.

"[It] will influence exchange with the United States, lamentably contrarily," he included, taking note of how the US as of now has "enough trouble with the European Union."

"We are splitting down right now on the European Union since they have not treated the United States decently on exchanging."

Adding to his unprecedented takedown of May, Trump commended Boris Johnson, who ventured during this time as outside secretary over Brexit.

"I'm not setting one against the other," Trump said. "I'm simply saying, I think he'd be an extraordinary head administrator."

Trump wanted to meet with May again Friday for lunch and the two were planned to hold a joint public interview.
