A 22-year-old man has been convicted of inciting racial hatred after he published antisemitic material.
Joshua Bonehill-Paine was described in court as “an extremist” who had expressed “virulently racist views in respect to the Jewish community”.
He had been arrested ahead of a planned neo-Nazi rally which was due to take place at the heart of the Jewish community in Golders Green, north-west London, in July.
Bonehill-Paine, of Yeovil, Somerset, had circulated images online including one which described the protest as an “anti-Jewification” event.
It carried a picture of a weed-killer being sprayed at a concentration camp.
He was convicted at Southwark Crown Court on Wednesday. He will be sentenced on Thursday.
A Community Security Trust spokesman said: "CST is proud to have played its part in the initial arrest of this troublemaker for the hateful image.
"We welcome his having been found guilty, but it is dreadful that he was able to harass and abuse so many people over all this time."
