In the aftermath of the New Zealand terrorist atrocity, a Labour MP has demanded "robust action, not words" against a neo-Nazi radio station broadcasting anti-Jewish and anti-Muslim hate material on social media.

Stephen Doughty, a member of the Home Affairs Select Committee, told the JC he had met with Home Secretary Sajid Javid on January 16 to discuss Radio Aryan's continued presence on Facebook, Twitter and YouTube.

Transmitted from a secret location in Britain, Radio Aryan attacks Muslims, describes Jews as "Yidflies", black men as "negro rapists" and broadcasts daily readings from Hitler's Mein Kampf.

Mr Doughty confirmed he had "specifically raised" the issue of channels such as Radio Aryan with the Home Secretary, and at an earlier meeting with Security Minister Ben Wallace on December 12 last year.

And only two weeks ago, the MP said he had met with Facebook executives urging them to take decisive action to stop hosting the neo-Nazi station - which has lauded the manifesto of Brenton Tarrant, who is accused of carrying out the killing of 50 Muslims at two Christchurch mosques on Friday.

Mr Doughty said: "There has been no substantive action, or legislative change taken against the social media companies as far as I can see," he said.

"Robust action is needed - not words."

In January, the Mail on Sunday reported that British far-right extremists were broadcasting vile racist programmes on Radio Aryan – but Government regulators are powerless to shut it down.

Jeremy Bedford-Turner, an ex-soldier, was revealed to be a major sponsor and contributor to the station.

Another key contributor of Radio Aryan is Laurence Nunn, 65, an ex-City financier who was previously an organiser for the BNP.

The station has broadcast material from members of the now proscribed National Action neo-Nazi organisation.

Broadcasting regulator Ofcom cannot intervene because it does not regulate any of the platforms Radio Ayran appears on.

Mr Tarrant openly referred to broadcasts on far-right online channels in his sordid manifesto, written ahead of the Mosque attacks which have shocked the world.
