NIGEL Farage has branded Joe Biden's election debate performance "worse than anyone can believe".
The Reform leader, and Trump ally, told The Sun that the US president is "totally unfit for office."
His intervention comes as Labour leader Sir Keir Starmer refused to comment on the President's worrying performance.
Biden, 81, locked horns with former President Donald Trump, 78, in the first showdown of the 2024 election cycle but stumbled over his words.
Leading into the debate, questions swirled about the president's fitness for office following a string of gaffs, blunders, and episodes where critics said he looked frail.

The president's health has been a hot topic throughout his presidency, with voters asking whether he can manage another four years in office.
Those fears were reignited on Thursday, with Biden stumbling through his sentences, speaking hoarsely, and appearing to freeze on stage.
Biden struggled throughout to overcome the early blunders.
At one point he trailed off mid-sentencing, saying: "Making sure that we're able to make every single solitary person eligible for what I’ve been able to do with the, with the Covid, excuse me, with dealing with everything we have to do with, look…"
"Look, if, we’ve finally beat Medicare," he added, before CNN's Jake Tapper ended his turn with, "Thank you, President Biden."
Biden also stumbled when talking about billionaires and immigration with his opponent admitting during the debate that he could not understand the president.
Sir Keir would not comment on the dire showdown, saying this morning: “I have to say I’ve got enough on my hands with my own election campaign to go too far into that.
"In the end, the person who is president of the US will be determined by the American people in due course and if we’re elected into government to serve, we will deal with whoever is the president.
"The relationship between the UK and the US is strong, it’s historic and obviously it’s above the individuals who are in office.”
Asked if he was worried about Biden, he said: “Well, look, I don’t think me commentating on the American election is helpful. We’ve got our own election going on here.

"And in the end it’s not for me, it’s for the American people to decide and they will decide and we’ll deal with whoever they elect in as their president.”
David Plouffe, a Democratic strategist and former Obama campaign official, called the debate “kind of a Defcon 1 moment.”
Vice President Kamala Harris admitted after the debate that her boss had "a slow start," but insisted there was "a strong finish."
"People can debate on style points but ultimately this election... has to be about substance and the contrast is clear," she said during a post-debate interview on CNN.
