The BBC has spoken to two former Dulwich College pupils who have backed up Mr Ettedgui’s version of events.
In response to Mr Ettedgui’s claims to the BBC, Farage told GB News: “I categorically deny saying those things, to that one individual, and frankly, frankly for the Guardian and the BBC to be going back just shy of half a century to come out with this stuff it shows how desperate they are.”
In a previous interview on Monday, Farage said he had probably “misspoken in my life, in my younger days, when I was a child”.
But he insisted he had not “directly racially abused” anyone “by taking it out on an individual on the basis of who they are or what they are”.
Asked if those making the allegations about him were telling the truth, he said: “Well, suddenly after 49 years they seem to have perfect recollection. I would say to you there is a strong political element to this.”
Pushed again on whether they were telling the truth, Farage said: “No, they are not telling the truth.”
After watching Farage’s denials in Monday’s BBC interview, Mr Ettedgui told the BBC: “This is a man who has power, influence, has had a massive impact on the direction of this country, for which, you know, hats off to him.
“And he is being fundamentally dishonest in everything that he says there. So I feel upset and angry about that.”
Mr Ettedgui is one of more than a dozen former Dulwich College pupils from the late 1970s and early 1980s who have claimed they witnessed Farage being racist.
As someone who sat near the future Reform leader in Class 3R at Dulwich College, Mr Ettedgui says he can clearly remember antisemitic abuse being directed at him, something he says he had never experienced before.
“One of the most vivid memories of my school life is Farage repeatedly coming up to me and, knowing that I was Jewish, saying Hitler was right and ‘gas ’em’, and that was frequently followed by a ‘sssss’, you know, kind of imitating the sound of escaping gas.
“That’s my abiding memory of him, and that sort of verbal abuse happened quite consistently over the year that we were together in the same class.
“And it was pretty vicious, it was pretty nasty, it was absolutely directed in a very personal way at me.”
He said Farage’s words had “hit hard” because his grandparents had escaped Nazi Germany and much of their family had perished in the Holocaust.
“It wasn’t the normal sort of vaguely antisemitic banter that you might encounter in the school grounds at that time in the 1970s. It was much worse,” he added.
Asked how he could be sure that his memory was correct, given that the events he describes happened many decades ago, Mr Ettedgui said: “I think anyone who suffers any kind of abuse, it’s going to mark their lives.
“And I carry that memory with me very, very strongly.”
He also hit back at Farage’s claim that he was a “child” at the time of the alleged incidents.
“We were teenagers, which in many religions is the age where you turn your gaze towards the adult world,” he said.
He added that the teenage Farage was “very well-informed” and “had a sense of history and politics already at that time”.
He rejected claims that his allegations were part of a politically motivated smear campaign, saying that he had “a deeply personal motivation” to speak out now because the idea of Farage becoming prime minister was “repellent and horrifying” to him.
“Is Farage saying here that around 20 people who go on the record, who either experienced or witnessed this kind of abuse, are we all lying?” he asked.
“Is this some sort of conspiracy between us all? Well, I can tell him right now, we haven’t spoken to each other. We haven’t coordinated this in any way.”
