Sadiq Khan to be Labour’s candidate for London mayor

“I want to reach out for support from every community, not win by divide and rule. A strained relationship with one of London’s most important minority communities is unacceptable,” he had said.

"I share with the Jewish community their concerns over the rise of antisemitic attacks on Jews and on synagogues here in London.

“It’s disgraceful that here in 21st century London we have guards outside schools and synagogues protecting them. Antisemitism, like racism, is vile. I stand shoulder to shoulder with the Jewish community.”

In June Mr Khan co-sponsored an early day motion in Parliament praising the efforts of campaigners to ban the a neo-Nazi protest planned for the heart of the north-west London Jewish community.

The other candidates were David Lammy and Diane Abbott.

Jay Stoll, of the Jewish Leadership Council, tweeted that his experience of working with Mr Khan suggested he was "a mensch with our best interests at heart".

Polling in recent months has shown Londoners favour the leading Conservative candidate, Zac Goldsmith, ahead of Mr Khan.
