A former member of an illegal white supremacist group has been caught on camera saying that murdered MP Jo Cox deserved to die.

Prominent National Action activist Garron Helm, who was jailed after tweeting anti-Semitic abuse in 2014, was filmed talking to an undercover reporter as part of an ITV news investigation into the group.

He is heard saying that Mrs Cox – a human rights campaigner and activist - “did have it coming” when she was brutally murdered in 2016.

Helm was filmed at a weekend “survival camp” in the Peak District attended by a number of people with links to National Action and other far-right organisations.

National Action was banned by the Home Office last year - meaning that it would be a terrorist offence for it to exist and could carry a jail term of up to ten years.

Before it was criminalised, the group had celebrated the death of Mrs Cox who was murdered on her way to her MP surgery in Birstall.

Helm was secretly filmed discussing the murder of Mrs Cox and claimed police used the MPs death to pursue National Action.

He said: “It was after that camp we did last year that they really came down on us, and then Jo Cox got murdered didn’t she? So they just used that as a f***ing excuse to come after us.

“It’s not our fault she was killed, I mean she did have it coming.”

The 23 year-old added: “You see a lot of the lads are bitter over it. I mean some of the areas they are growing up in are so rough and so infested with you know, ethnics, that they’ve literally got no tolerance for people anymore they believe to be committing treason.

“I do think if you’re committing an act of treason against, you know, your own ethnic group then by right you should be put to death.”

National Action adopted the words of Mrs Cox’s killer “death to traitors”, as its motto.

In 2014 Helm, from Liverpool, was jailed after sending an anti-Semitic tweet to Jewish MP Luciana Berger.

The offending tweet showed a Nazi-style yellow star superimposed on Ms Berger’s face with the words '#Hitler was right'.
