A coalition of Shoah survivors has publicly demanded that Nigel Farage admit the facts and issue an apology for alleged antisemitic comments attributed to him toward Jewish schoolmates during his youth.
The political party leader has previously stated he never racially abused anyone with deliberate cruelty, framing it may have been mere "schoolyard talk".
"Being Holocaust survivors, we understand the deadly peril of bigoted language – because we have seen where such words inevitably end," wrote the survivors in a open letter.
"Let us be clear: praising Hitler, mimicking gas chambers, or hurling racist abuse is not banter. Not in a playground. Not anywhere."
The correspondence puts forth straightforward questions to the party leader: "Did you say ‘Hitler was right’ and ‘gas them,’ and mimicked gas chambers? Did you target your fellow pupils to antisemitic abuse?"
The group of 11 survivors includes individuals with deeply traumatic personal histories from the Holocaust.
The remaining survivors include Janine Webber, Edith Jayne, Helen Aronson, Ruth Barnett, John Fieldsend, Susan Pollack, Hanneke Dye and Agnes Kaposi.
This intervention is a response to the rejection of corroborating accounts by more than several dozen former pupils and teachers as "fabricated nonsense" by a senior party figure.
Since the initial report, more contemporaries have come forward. Twenty-eight people connected to the school now claim they observed bigoted conduct by him.
One well-known account comes from Peter Ettedgui, a Jewish award-winning director, who recalls that a teenage Farage would sidle up to him and utter the phrases "Hitler had the correct idea" and "gas them", at times making a long hiss to mimic the sound of poison gas.
Additional alumni from ethnic minorities have also come forward with allegations of personal harassment.
The final appeal puts forth an ultimate challenge to Farage: "By denying saying those words, is your position that 20 former classmates and teachers are not telling the truth? If you did say them, now is the time to acknowledge you were wrong and make amends."
"Individuals who seek to govern our country should under no circumstances sow discord by background or belief. Hatred of Jews must always be confronted. This moment is about ethical duty. The decision is yours, Mr Farage."
