David Baddiel struggled to contain his anger during a dramatic confrontation with a Holocaust denier, who accuses Jewish people of 'hating Europeans', 'sacrificing Christian babies' and 'controlling the BBC' in a new documentary.
The comedian, 55, from London, whose mother Sarah escaped to the UK from Nazi Germany as a newborn with her parents in 1939, explored the subject for Confronting Holocaust Denial, which aired on BBC2 on Monday night.
He met with with Irish Holocaust denier Dermot Mulqueen, a failed independent politician who describes himself as an 'artist', who charges for anti-Semitic songs on his website.
Mulqueen told David that Auschwitz 'didn't have gas chambers', and claimed that Jewish people buying cars from German companies is proof the genocide didn't happen.

David confessed that while he felt uncomfortable meeting with a Holocaust denier, he felt it was necessary in order to understand the phenomenon, and so chose Dermot, who had been in contact with him prior to the documentary.
After admitting that he would find it difficult to remain objective in the interview, David began his talk with Dermot by listening to the Holocaust denier claim that 'the whole narrative' around the genocide is false.
'When you examine it like I have done, there were no homicidal gas chambers,' said Dermot.
'There were 15 ovens, you can fit one or two maximum in at a time and it takes an hour to burn a body. Okay? So it's just not possible.'
Dermot Mulqueen is an online Holocaust denier from Ennis, in Country Clare, Ireland.
He ran a now deleted Facebook page under the moniker 'President Mulqueen'.
He regularly shared memes about the Holocaust and claimed the genocide did not happen.
His page offered 'alternative tours of Auschwitz with alleged facts about the camp.
In 2015 was arrested after putting an axe through a TV in the main square, in protest at Holocaust Memorial Day.
He told Ennis Circuit Court court he wanted to launch 'International Holocaust Hoax Day'.
He was found guilty of breaching section nine of the Firearms Act and section six of the Public Order Act.
In December 2015 his five-month sentence was suspended.
Dermot describes himself as 'an artist' and writes political songs that can be found on his YouTube channel or purchased on his website.
In 2016 he ran in the General Election to represent Clare (Dáil constituency) as an independent MP
He claimed on his Facebook page at the time that he would be demanding the reinstatement of 'Direct Democracy' if elected.
He told he would reinstate Article 48 from the Constitution of the Irish Free State, which was removed in 1928.
This would enable a form of democracy in which people decide on policy initiatives directly.
