Jean-Pierre Lihou, 61, was initially friends with the Reform UK leader when he arrived at Dulwich College in the 1970s, at the time when Mr Farage is accused of saying antisemitic and other racist remarks by more than a dozen pupils.
But Mr Lihou, who is half-German and said he went for a couple of sleepovers at Mr Farage’s parent’s house, told Sky News’ Amanda Akass that it “soon become obvious he was not quite the same person I thought he was”.

Another former pupil, Stefan Benarroch, who was in the year below Mr Farage and is Jewish, said that Mr Farage was “not a kid” when he made alleged antisemitic remarks and his behaviour was “unacceptable in any era”.
Mr Farage has said he “never directly racially abused anybody” at Dulwich and said there is a “strong political element” to the allegations coming out 49 years later. Reform’s deputy leader Richard Tice has called the ex-classmates “liars”.
A Reform UK spokesman accused Sky News of “scraping the barrel” and were “desperate to stop us winning the next election”.
Mr Lihou told Sky News Mr Farage used to direct antisemitic songs at his Jewish friend Peter Ettedgui, who is one of the main former classmates to have spoken out against the Reform leader.
“He used to sing: ‘Gas them all, gas them out, gas them all, into the chambers they crawl’ – and the rest of those horrible words,” he said.
“You think, when somebody is obviously distressed by that, why do you keep doing it? The humour wears off… when you see this, and because I’m German I’m particularly sensitive to anyone making that kind of analogy.”
Mr Lihou also said Mr Farage used to “pass comment on anyone that wasn’t white, particularly Indians”.
He said: “He had a great big issue with anyone called Patel because I think the school had at one point more Patels than Smiths. That seemed to irk him.
“Anybody who wasn’t white, he was likely to have a comment pretty much throughout my school life, especially Jewish people. I think that was the worst thing because you could obviously see that people were hurt by it.”
