The Labour Party has expelled four far-left groups that were strong supporters of Jeremy Corbyn after its ruling committee decided they were 'not compatible' with the party's values.
According to multiple reports, the organisations - Resist, Socialist Appeal, Labour in Exile Network and Labour Against the Witchhunt - were proscribed during a National Executive Committee meeting on Tuesday.
Insiders said some of the groups were directed by people who had been expelled from the party, while others had described work to tackle anti-Semitism as a 'witch-hunt' or a 'smear' campaign.
The Mirror, which broke the story last week, said as many as 1,000 members could see their membership revoked as a result of the purge.
