A day of action to celebrate diversity is being planned for Friday July 3, 24 hours before extremists are set to hold a rally in Golders Green against "Jewish privilege".
London Jewish Forum and the anti-fascist organisation Hope not Hate have jointly launched Golders Green Together as a show of unity against the rally.
The static protest, promoted by the far-right New Dawn Party and which Home Secretary Theresa May spoke out against this week, is due to take place on July 4 - a Shabbat.
In its first statement, Golders Green Together strongly condemned the extremists behind the rally.
It said: “Their aim is to spread fear and division, to fracture the peace and good neighbourliness that exists between our communities and to insult the memory of those who died at the hands of their murderous forebears.
“We believe that the most effective response we can have to this provocation is to show our communities reject the politics of hatred, and instead stand together.”
The group, which is supported by the Board of Deputies and is consulting with the Community Security Trust, launched its Twitter account, @GG_Together, on Thursday and has planned a programme of activities over the month to promote diversity.
Jonny Newton, CST’s senior public affairs manager, said the campaign was “a call to action.
“It's the communal response to the July 4 demonstration, and it’ll be a dignified and appropriate response to it.
“We’re trying to get as many civic, religious and political communities as possible to stand together, to show the unity of the Golders Green Together campaign in the face of provocative action.”
Organisers are encouraging the community to decorate Golders Green with gold and green ribbons on July 3 to show "we are a strong, diverse and united community".
People will also be asked to use social media to upload and share photos that represent togetherness, "in a declaration of unity".
Leaflets promoting #goldersgreentogether will be distributed to homes in the area, and organisers are planning to produce an eight-page community newspaper with contributions from residents.
