Well this just got interesting.Lisa Nandy will stand against Corbyn, Labour source tells me.— George Eaton (@georgeeaton) 27 June 2016
I think Lisa should have waited. Not quite seasoned enough.
And, bluntly, who would want to be leader just now. There is going to be a massive, very bitter war between the parliamentary party and the membership. If she wins with one, she'll lose with the other. And given the PLP has shown itself to be totally inflexible and self-destructive, I don't see how her brand of mild leftism will be accepted.
They'll scheme and worry her to destruction, like they are doing / did to Corbyn, Milliband and Brown.
