Clive Sheldon QC will take an especially keen interest in the outcome of Labour’s disciplinary inquiry into Ken Livingstone, which is due to be announced today.

He is the barrister who acted for Labour, presenting the case at the inquiry that the former Mayor of London had brought Labour into disrepute nearly a year ago for claiming that Hitler supported Zionism.

A leading Masorti activist who chairs the New Israel Fund, Mr Sheldon is a Labour member who successfully represented the party’s national executive committee last summer in a High Court Case over who was eligible to vote in the party’s leadership election.

In December, he was asked by the Football Association to head its inquiry into allegations of historical child sexual abuse in football.

The former Habonim member, who spent a gap year in Israel and was a campaigner for Soviet Jewry in his student days, has urged Jews not to abandon Labour but to work with the party to confront the challenges within it.
