The open letter, organised by the Together Coalition, said: “The spectre of Jewish people being stabbed at random in the street, killed defending their synagogues and Jewish infrastructure being firebombed feel like a nightmare from another time.”
It added: “This is not a problem for Jewish people to have to respond to. This is a problem for all of us to fix.
“This country belongs to you as much as any of us. You are as British as all of us who call this country home. And we will do everything we can to protect you and your community from the extremists who threaten you.”
Responding to the letter, Chief Rabbi Sir Ephraim Mirvis called it a “powerful riposte to the hateful extremists who have targeted the Jewish community”.
“My hope is that where these institutions have led, others will follow, in workplaces, boardrooms, classrooms and on social media, so that we can finally begin to tackle this scourge together,” he added.
