Sadiq Khan has urged victims of anti-Semitism to speak out as he voiced his support for Jewish communities.
The Major of London insisted he had a zero tolerance stance on hate and that any such incident should be flagged to the police.
Mr Khan said he and Met Police Commissioner Cressida Dick were clear that anti-Semitism would be acted upon.
Asked what he would say to Jewish communities who felt concerned by targeted incidents, he told the Standard: “Please report any incident of anti-Semitism to the police.
“Don’t think it’s trivial or it doesn’t matter - it does.”
There have been a number of recent anti-Semitic attacks in London, while figures from the Community Security Trust showed that such hate incidents were by 16 per cent in 2018.
Mr Khan’s comments came following a Jewish Labour Movement rally at this year’s Labour Party Conference in Brighton.
He addressed crowds in the Middle Street Synagogue, a Grade II listed building, near to the main conference centre and said it “broke his heart” to see people scared of being targeted with anti-Semitic hate.
Speeches at the event were dominated by the issue of anti-Semitism within the Labour Party and addressing this, Mr Khan said: “My concern about our party is that there appears to be a hierarchy when it comes to racism.
“Racism is racism. Anti-Semitism is racism.”
Towards the end of his speech, he said: “We are with you, we stand with you in solidarity. We will win this battle.”
The Labour Party has been gripped by an anti-Semitism crisis, with other speakers criticising how the issue has been tackled and calling for a “truly independent” complaints body.
Despite the continuing criticism, the Labour Party and leader Jeremy Corbyn have insisted they are committed to rooting out anti-Semitism and those who spread it.
