We revealed earlier this week how Carl Mason, who is standing in the Nunnery ward in May, has quit as the city’s BNP organiser to launch a new right-wing group called the ‘British Resistance Party’.

But the controversial figure, who was questioned by police last Saturday after stickers linking the Labour Party to paedophiles appeared on lampposts, is now coming under fresh scrutiny for his online blogging.

The 50-year-old is a writer on a website called the ‘European Knights Project‘, which claims to provide a platform for people looking to “preserve Christian culture”.

On it Mr Mason, who boasts about waging “a one-man war against multiculturalism”, says many Germans were jailed for “doing little more than following orders”.

He also refers to the documented history of the Einsatzgruppen, where Nazi death squads were responsible for the mass slaughter of Jewish people, as wrong – saying “they did no such thing”, claiming the Germans instead shot “Communists” as a “revenge” for allied forces taking their farms, factories and homes.

He also cites doubts about several other elements of the Holocaust, before suggesting a conspiracy is at play to fool people.

“Could it be to control people’s voting habits, and in turn keep certain political parties in power, and in the money,” he writes.

“Is it being done in a manner so we feel sympathy towards the people that control our money supply, run our banks and media, so people are socially conditioned to hating people like me?

“Recall whenever a patriot is referred to as a ‘Nazi’, an image of shrunken heads and skin lampshades immediately pops up.”

Other online posts also bring up similar rhetoric, and on his official resistance party’s website he calls himself its “security adviser”, using the slogan: “Enough is enough – attack one of us, attack all of us – meet the British Resistance, our organisation and nation’s last line of defence.”

He also refers to wanting to “stand against Islamism, Zionism and British traitors”.

Mr Mason has told this newspaper he was “not denying the Holocaust” but admitted writing the posts because of doubts over the official narrative.

“If I wrote that in 53 countries I’d be arrested, that’s why the site is hosted in Russia,” he said.

“I’m not denying the Holocaust, as such but I’m asking questions – I think it did happen, but it was different to what history says.”

Worcestershire MEP James Carver, who is of Romanichal descent, has called it “despicable”.

“It’s disgusting, the historical facts about the Holocaust are clear,” he said.

“I know Holocaust survivors personally, this is just despicable – I know the stories and the heartbreak.”

West Mercia Police are taking no action against Mr Mason for the stickers linking the Labour Party to paedophiles, after he denied sticking them on lampposts.

He did, however, admit to printing off “around 2,000” to sell to other people.
