Undeterred by his waning power over the extremist right-wing in the UK, Nick Griffin has kept with his cause by declaring that Russia will save “Christendom”.

The former BNP leader was expelled from the organisation last year, after members accused him of attempting to “destabilise” it and of “harassing” its membership.

Griffin responded by accusing the party leadership of playing “plastic gangster games”.

At the International Russian Conservative Forum in St Petersbury over the weekend, which was organised by a pro-Kremlin ultranationalist party, Griffin warned the audience that Christendom would succumb to “a terrible civil war”, become and Islamist caliphate “or perhaps both”, BuzzFeed reported.

He added that “the survival of Christendom” is “absolutely impossible without the rise of the Third Rome: Moscow.”

Roberto Fiore of Italy’s Forza Nuova, mirrored Griffin’s comments at the event, and claimed that Moscow is currently the only nation guarding what he regards to be Western values in the way Rome once did.

“It’s not me saying this—it’s God saying it,” he said, the Wall Street Journal reported.

In an interview with the US newspaper, Griffin said Russia is “more free” than the West as a similar event would be banned in the US or the UK.

Other guests included Udo Voigt, a senior figure in Germany’s extreme-right National Democratic Party, and members of the ultra-right Greek party Golden Dawn.
