Police have charged Joshua Bonehill-Paine with inciting racial hatred ahead of a neo-Nazi protest due to take place in north-west London next week.
Bonehill-Paine, 22, of Yeovil, Somerset, has been held in custody and is due to appear at Westminster Magistrates’ Court on Monday.
He had claimed to be one of the organisers of the neo-Nazi rally planned to take place in Golders Green on July 4.
Earlier this week a series of offensive images and comments appeared on his website .
One image showed the walls of Nazi concentration camp Auschwitz-Birkenau and a can of weed-killer.
It carried the words: “Liberate Golders Green: An anti-Jewification event. We’ve become complacent and allowed for weeds to grow in the cracks of London. It’s time to clear them out with round-up and liberate Golders Green for future generations of white people.
“Join us on July 4 for what promises to be an absolute gas!”
A second image showed an emoticon designed to look like Hitler and read: “Hey kids! We’re going to Golders Green on July 4 for a party. Join us for what promises to be an absolute gas!”
Last week he had claimed supporters were planning to burn copies of the Talmud ahead of the event.
He was arrested on Friday by officers from the Metropolitan Police working with colleagues in Barnet and Somerset.
Before being taken into custody he wrote online: “A few months in prison is absolutely no consequence to me, I’d be back out to continue leading the Anti-Jewification initiative and my voice will remain strong.”
A police spokeswoman said: "Officers continue to assess all information and intelligence available in relation to the proposed demonstration and speak with the organisers to ensure we have an appropriate policing response in place.
"We are aware of concerns in the local community about the negative impact this proposed demonstration may have on them and are working with residents to ensure that people can exercise their rights in a way that is lawful, while minimising this impact."
