Toby Young has a cunning plan in the Telegraph:

“The size of the Labour leadership electorate is projected to be 240,000 or thereabouts, so quite large. Second preferences are redistributed and, assuming Liz Kendall’s eliminated first, followed by Yvette Cooper, I can’t see him getting many of those. To win, therefore, Corbyn would need to get close to 50 per cent of first preferences – quite a tall order, even in a party as batshit crazy as Labour.

But that doesn’t mean 120,000 Tories will have to vote for him. Incredibly, Corbyn is quite popular with Labour’s grass roots. He was the overwhelming favourite in a recent LabourList poll, attracting a whopping 47 per cent of the vote, compared to 13 per cent for Burnham, 11 per cent for Kendall and nine per cent for Cooper. If that holds up, he could win as many as 40,000 votes without any help from us. That means only 80,000 #ToriesForCorbyn need to sign up to put him over the top. Note to Lynton: You can buy the next election for just £240,000.”

Guido suspects this could go the same way as Toby’s Tory/UKIP pact plan, but all good fun.

The Guardian have had a characteristically po-faced reaction to the campaign:

“Conservative party supporters have mounted a Twitter campaign to elect Jeremy Corbyn as Labour leader in order to damage the party’s future election chances. According to new rules, anybody can pay £3 to register as a Labour supporter and vote for the new leader, a change that some speculated would leave the process open to abuse by opponents.”
