Asked if the former president would forgive Labour boss and Prime Minister Keir Starmer, Farage said: “Ultimately, but maybe not for a bit. And why get the relationship off to a bad start? It’s ludicrous.”

The governing Labour Party is currently embroiled in a row with Trump’s campaign, which filed a compliant with the Federal Election Commission this week accusing Labour of foreign election interference.

It comes after Labour activists traveled to the U.S. to volunteer for the vice president’s campaign. Labour has stressed that its staff were heading stateside in their own time and that the party is not paying for their travel or accommodation.

Farage said Thursday: “Trump’s going to win. I’m 90 per cent confident of that. And this country, our relationship with America… This relationship is our most important relationship in the world. And for a newly elected governing Labour Party to actively be seen to be backing the other side in an election, is a very big political mistake.”

Farage has visited the U.S. numerous times to campaign alongside Trump. Asked whether anyone else had ever paid for his flights stateside, Farage said: “Not if I was going to actively involve myself in the Trump campaign, no.

“I’ve always paid my own way and always been very conscious of what American electoral law is.”
