Shadow Chancellor John McDonnell is president of a group campaigning on behalf of Ken Livingstone and a party activist expelled for verbally abusing MP Ruth Smeeth.
The group is the Labour Representation Committee, which has posted a lengthy statement on its website backing Mr Livingstone, describing him as the victim of a “witch hunt” over his comments about Hitler and Zionism.
The LRC claims the remarks Mr Livingstone eventually resigned from the party over were "not remotely antisemitic".
It has also created a page on its website promoting a national speaking tour by Marc Wadsworth, who was expelled from the party in April for his verbal attack on Ms Smeeth at the launch of the party’s report into antisemitism.
