THE threat from British neonazis “remains high” six years on from the murder of Jo Cox by a far-right gunman, an expert on right-wing extremism warned today. 

Speaking on the anniversary of the Labour MP’s death, Professor Matthew Feldman said society should remain vigilant to “lone wolf” attacks despite the dismantling of the far-right National Action (NA) group. 

The neonazi organisation was proscribed as a terrorist group for glorifying the murder of Ms Cox, who died after being stabbed and shot by Tommy Mair outside her constituency office in Birstall on June 16, 2016. 

Nazi regalia and far-right books were later found at Mr Mair’s house. 

Nineteen NA members have been convicted in the years since, including founder Alex Davies, who was jailed for eight-and-a-half years for his role in the proscribed group at the Old Bailey last week. 

Prof Feldman gave evidence in Mr Davies’s trial, as well as at 15 other similar cases over the past four years. 

The expert said that while the ability of the far right to achieve their aims by violence is “virtually nil,” he warned that “doesn’t mean that the threat of neonazism and fascist activism more generally has gone away.”

Following the murder of Ms Cox, the 2019 Christchurch mosque attacks in New Zealand and the recent mass shooting in Buffalo in the US, the risk “remains high,” he said.

Founded in 2013 and banned three years later, the ethos of NA was “Hitler worship, fascist revolution and ethnic cleansing of ethnic and religious minorities,” he said. 

The group forged international links with other neonazi groups in the United States, Australia, Finland and Ukraine. 

Prof Feldman said: “After the group was proscribed, there’s clear evidence that a militant from National Action, who was later convicted of having been a member post-proscription, travelled to Ukraine to meet with the [far-right militant] Azov Battalion.

“I know of one for certain but there may well have been more.”

He added: “It’s really important that people recognise things have changed since the illegal invasion of Ukraine by Russia.

“But, for a long time, the vanguard of defending Ukraine in Europe were people who had a very high percentage of extreme right, even neonazi militants, and those people were coming from all over the world.”

Convicted NA members have included British soldier and Finnish-born Mikko Vehvilainen and former Metropolitan Police constable Ben Hannam.
