"In a 2005 essay, Mr [Paul] Eisen detailed his support for a jailed German ­Holocaust denier; "rehumanised" Adolf Hitler; and insisted being a Holocaust denier was an "entirely ­honourable thing". His claims prompted a number of DYR [Deir Yassin Remembered] directors to withdraw from the group. In 2007, the Palestine Solidarity Campaign (PSC) cut its links with DYR over its anti-Semitism although Mr Corbyn, himself a patron of PSC, attended at least one further event in 2013 organised by Mr Eisen and Mrs Kaffash. They had been publicly ­exposed as – or else admitted to being – Holocaust deniers prior to Mr ­Corbyn's decision to denounce DYR. Tracked down by The Telegraph, Mrs Kaffash, 78, a co-organiser of its annual event commemorating an alleged ­massacre of Arabs at Deir Yassin in 1948, said: "Jeremy was a stalwart of DYR... a very important supporter. You can rely on Jeremy. He came to this house and sat in that chair." She claimed to The Telegraph that in her view: "He could not not know what Paul's views were. Or mine." Asked about her views of the Holocaust, Mrs Kaffash, who denies being anti-Semitic, said: “I don’t think there is evidence gas chambers were used to exterminate Jews. I don’t think there is evidence of a policy of extermination.""
