Last week Labour sought to nip the #ToriesForCorbyn campaign in the bud by insisting everyone voting must “support the aims and values of the Labour Party and if they don’t then they won’t be allowed to take part”.

Since then, the only change made to the process has been to ask participants to agree to this statement:

“I support the aims and values of the Labour Party, and I am not a supporter of any organisation opposed to it.”

Yet Labour NEC veteran Ann Black last night admitted that the new system would not stop Tory entryists:

“Some members are concerned about registered supporters and whether our political enemies can subvert the process… Of course people can always lie”

The Corbyn campaign is now seeking to allay concerns:

“much has been made of the idea that Tories are joining the party to vote for this or that candidate. Our instincts tell us to be suspicious of a storm whipped up mainly by the Tory Press. We doubt if it adds up to much.”

He might doubt it, but he’ll be hoping that it does…
