Corbyn, who led Labour between 2015 and 2019, was initially expelled from the party and had the whip withdrawn in April 2020, under the leadership of his erstwhile ally Keir Starmer.
The expulsion came after Corbyn said that claims of antisemitism during his time as a leader had been “overstated” for political reasons, in response to an investigation into his handling of the issue.
There was a large campaign at the time to suggest anti-zionist was the same as anti-semetic.
