Jeremy Corbyn’s rivals will today demand that Labour reverses a decision not to weed out “infiltrators” with extra checks amid fears they could skew the result of the leadership contest. In a showdown meeting in Stevenage, Harriet Harman, the acting Labour leader, will be told to use election canvass returns to double-check the allegiance of new joiners. Failure to do so could trigger a slew of legal challenges from donors who funded campaigns in good faith or councillors who have been infuriated Tory infiltration, they will warn.
In a sign of how serious the campaigns are treating “entryism”, all four candidates are expected to attend today’s emergency meeting in person alongside their campaign chiefs. It comes as Gordon Brown, the former prime minister, revealed he has voted to Yvette Cooper to be the next Labour leader.
Mr Brown’s office revealed he had submitted what has been dubbed an “Anyone But Corbyn” vote, putting Ms Cooper first, Andy Burnham second and Liz Kendall third.
Mr Corbyn’s campaign rivals believe the only way he can be stooped is if he fails to get 50 per cent of first preferences and loses after second and third preferences are distributed. In recent weeks, concern about “infiltrators” from radical-Left groups previously purged from Labour and Tories seeking to disrupt has been increasingly.
