Donald Trump launched an extraordinary rant against Europe yesterday(TUES), telling leaders: “Your countries are going to hell.”

In a speech to the United Nations, he said immigration was ruining European countries and urged Keir Starmer to open more oil fields in the North Sea, as he declared global warming a "hoax." He doubled down on his feud with Sadiq Khan, making a baseless allegation that the London Mayor was trying to impose Sharia law in the capital.

He said the UN was "not living up to its potential" and suggested it operates in a corrupt manner. Mr Trump arrived on stage complaining that the teleprompter was broken, and that an escalator had broken down on his way into the building. Delegates and observers chuckled as he recounted having bid on the contract to refurbish the United Nations HQ in New York.

"Many years ago a very successful real estate developer in New York known as Donald J Trump, I bid on the refurbishment of this very building," he said. "I'm going to give you marble floors, they’re going to give you terrazzo. I’m going to give you the best of everything, you’re going to have mahogany walls. They’re going to give you plastic"

He went on: "They spent between $2 and $4 billion and didn't even get the marble floors I was promising. Looking at the building and getting stuck on the escalator...they still haven't finished the job."

He claimed the bidding process was "so corrupt" that he had been asked to testify in a court case about the matter. He said: "Unfortunately many things in the United Nations are happening just like that but on a much bigger scale, it's sad to see."

He listed the seven wars he claims to have prevented or ended, but criticised the UN for "failing" to offer to help.

"It's too bad that I had to do these things instead of the UN doing them," he said. "And sadly in all cases the UN did not even try to help in any of them. I never even received a phone call from the UN offering to help in finalising the deal."

He went on: "All I got from the UN was an escalator that stopped in the middle, if the First Lady hadn't been in great shape she would have fallen. And now a teleprompter that doesn't work. That's what I got from the United Nations, a bad escalator and a bad teleprompter."

The US President added: "What is the purpose of the United Nations? The UN has such tremendous potential...but it's not even coming close to living up to that potential. For the most part all they do is write a strongly worded letter."

Trump also took a swipe at Europe over immigration, saying: "You're countries are going to hell.

He said: "Europe is in serious trouble. They've been invaded by a force of illegal aliens like nobody's ever seen before and nobody's doing anything to get them out. It's not sustainable.

He took aim at London Mayor Sadiq Khan, with whom he has a long-running feud. He said: "I look at London, where you have a terrible mayor, terrible, terrible mayor, and it's been changed, it's been so changed. Now they want to go to sharia law. But you are in a different country, you can't do that."

A spokesperson for Sir Sadiq said: “We are not going to dignify his appalling and bigoted comments with a response.

“London is the greatest city in the world, safer than major US cities, and we’re delighted to welcome the record number of US citizens moving here.”

Mr Trump also used the speech to urge Keir Starmer to open more oil fields in the North Sea, as he declared global warming a "hoax."

"Drill baby drill," he declared from the stage, before telling delegates and observers that the Paris Climate Accord, to which almost all of them are signatories, was "fake." He said : "All green is all bankrupt. It's not politically correct, I'll get criticised for saying it."

"What a tremendous asset for the United Kingdom," he said of the North Sea. "I hope the Prime Minister is listening."

He went on: "The North Sea, I know the North Sea so well. They essentially closed it by making it so highly taxed that no oil company can go there. And he repeatedly attacked one of his longest-running bugbears - wind energy.

Mr Trump has campaigned about wind farms for decades, since a well-publicised row with the Scottish government over windmills planned for near to one of his golf courses.

"I want to see them stopping ruining that great English countryside with wind farms," he said. "We're not doing that in America."

Speaking at the UN General Assembly in New York, he told delegates: "We're getting out of the falsely named renewables. They're a joke. The wind doesn't blow, the windmills they're pathetic."

Meanwhile, Mr Trump tore into UN delegates who recognised Palestinian Statehood at a special meeting last night. "The rewards would be too great for Hamas atrocities," he said. "The reward would be too great for these terrible tragedies."

He added: "Instead of giving in to [Hamas'] ransom demands, we should have one message: release the hostages now."

Delegates and observers applauded for the first time in his speech in response to this message. He added: "We have to stop the war in Gaza immediately, we've got to get it done."
