senior Labour figures who are concerned that the party’s vetting process is not robust enough to remove all entryists with only a week to go until the first ballot papers are sent out. The vote closes on September 10.
A Labour insider said that the party’s central operation had started to panic about the potential scale of entryism. It has attempted to strengthen the operation by drafting in staff from its headquarters in Westminster to do batches of vetting. There have even been rumours that the vote will have to be delayed.
On Wednesday Harriet Harman, acting party leader, wrote to MPs urging vigilance against entryism. Each Labour MP has been sent data on local new members to check for suspicious names and those who do not “share Labour’s values”. The failure to spot senior rival party members, many of whom stood against Labour figures in the election, is likely to cause concern.
Liz Davies was a member of Left Unity’s ruling body until this summer and has signed up to vote in the Labour contest without being detected. Although she claims she resigned from Left Unity when she registered, she is still listed online as a member of the party’s ruling body and has not been contacted by Labour to verify her status.
Mark Serwotka, the left-wing head of the Public and Commercial Services trade union, which has around 250,000 members, has also signed up undetected to vote, despite being a harsh critic of Labour in the recent past. He confirmed that he registered shortly after Mr Corbyn won a place on the ballot paper in June.
Labour refused to comment on individual cases, but a source insisted: “Anybody identified as a public critic of the party or seen to do it down will not be given a ballot paper.” It argued that it will verify all new recruits before the vote, checking them against the names of senior members of other parties.
All Labour leadership contenders and their teams have been given access to new recruits’ data to allow them to pitch to them. The data is updated weekly, with a list of blacklisted recruits passed on. It is understood that no banned recruits were passed on last week, while 700 were sent the week before and 50 the week before that.
The revelations follow reports yesterday that 100 Green party candidates had been caught having registered to vote in the Labour leadership contest.
