In the New Statesman, Neil Kinnock tells Corbyn he’s unelectable:

“It’s difficult to see that [Jeremy Corbyn is electable]. Many of the people who voted for Jeremy are outstanding party members who said that they were frustrated – indeed, infuriated – by the failure of Labour to connect with the electorate. I know exactly what they mean, but that’s the test… If Jeremy is seen to be failing to connect to the electorate after a reasonable space of time then he may come to his own conclusions… It’s difficult for him and those closest to him in the circumstances to acquire loyalty and to uphold unity… There’s a fundamental question here and it is whether people want to secure power in the party or to win power for the party. Those people who want to win power, whether they’re left, right or centre, will be watching the evidence and will make their decision on the basis of that evidence. Not because of some spasm of emotion, or the fact that their candidate didn’t get elected: they’ll want to know they have a party that is being led in its advance with the electorate. If that isn’t the case then conclusions must be drawn.”
