Far-right group New Dawn Party is thought to be planning a rally against the Jewish community in London.
A post sent from a Twitter account in the name of the group read: “Oppose the 'Shomrim' demo. Golders Green. Saturday July 4th Details to follow.”
A spokesperson for the Community Security Trust said it was aware of the proposed demonstration.
The organisers were thought to be the same group of far-right nationalists who staged a small rally against the Charedi community in Stamford Hill earlier this year .
