Yet again, the six-monthly figures from the Community Security Trust show a record number of antisemitic incidents — and a further ten per cent rise in the number recorded between January and June of this year and the same period in 2018. In all but two months since April 2016 there have been more than a hundred recorded incidents — a level of antisemitic abuse and attack that was previously seen only when Israel was at war.

But the cause of this ongoing record increase in antisemitism is no mystery. It can be summed up in two words: Jeremy Corbyn. So we address this directly to the Labour leader: Are these figures high enough for you, Mr Corbyn?

Because, by any objective analysis of contemporary British antisemitism, Mr Corbyn must be seen as the instigator. Over the almost four years of his leadership, Mr Corbyn has refused to take any meaningful action against antisemitism in his party and has merely mouthed platitudes.

But his is not a sin of omission; it is one of commission. His words may say one thing but his behaviour shows something very different. That behaviour has sent a clear message to racists that they are welcome in the Labour Party.

More widely, Mr Corbyn has injected a poison into British politics and turbocharged the levels of open antisemitism in British society.

These CST figures are Jeremy Corbyn’s legacy. They are the legacy of the most dangerous racist in British politics — a man whose toxic views and behaviour pose a far greater threat to ethnic minorities than the National Front or the BNP ever managed. The figures should shame Mr Corbyn.

But, as the past four years have shown, he has no sense of shame.
