On Yom Kippur we look back at our sins over the past year. As well as its religious significance for Jews, it is a useful and important step for anyone — and any organisation — to take. Unless we acknowledge how we have erred in the past there is no possibility of behaving better in future.

In that context, it is appropriate that the Labour Party Conference fell during the High Holy Days. Labour’s recent sins do not need rehashing. Save to say that it became the first mainstream party to be the subject of what ended up as a damning Equality and Human Rights Commission investigation.

Sir Keir Starmer has made dealing with Labour antisemitism a priority. He is clearly sincere in that aim — he mentions it repeatedly and did so again in his conference speech on Tuesday.

And he has made good progress. As our political editor reports this week, the atmosphere at Labour’s conference was generally welcoming and positive. Sir Keir and his allies can look back on the past year with some pride; they have indeed acted with purpose and determination to tackle antisemitism.

But there remains a long way to go. Sir Keir said that he had had “to rip antisemitism out [of the party] by its roots”. It is good that the audience applauded the sentiment loudly. But it is simply wrong to claim that the problem of antisemitism has been dealt with.

Anything but; Labour members elected to the party’s NEC a leading light of Jewish Voice for Labour, an organisation set up specifically to deny that there was any such problem. She is, ironically, unable to take her seat on the body as she has been suspended for speaking at a meeting held by a proscribed organisation.

This was a good week for Labour and for Sir Keir. But it is only the start of what needs to be done, not the end.
