A former neo-Nazi recalled his time in the BNP, National Front and Combat 18 at a Young CST dinner.

Interviewed by Sky News political editor Adam Boulton, Hope Not Hate's Matthew Collins spoke about the violence within far right groups - and his escape to Australia after agreeing to expose the activities of Combat 18.

"There is no standard or staple antisemitism," he told the 230 guests. "It will creep into the mainstream whenever and wherever it can.

"The BNP would still exist even if immigration stopped completely."

He also warned that "Holocaust denial seeps into the mainstream through false calls for free speech".

Another speaker was ex-Hizb ut-Tahrir activist Shiraz Maher who now works for the International Centre for the Study of Radicalistion at King's College London. He alleged that the organisation had a "sharp antisemitic focus".

The dinner was the third event from the CST's young committee, aimed at the 25-35s, since its launch a year ago.In July, Gwyneth Paltrow was the special guest at its summer cocktail party.
