At least a dozen of last year’s nominators never had any intention of voting for Corbyn. It is safe to say that if any of those dozen could have predicted Corbyn’s victory then no amount of pressure from their more left-wing activists could have persuaded them to “broaden the debate” by “lending” him their nomination.

But they couldn’t foresee the future. They failed to understand that the move from the electoral college – where MPs, ordinary members and affiliated organisations (mainly trade unions) each wielded a third of the vote – to a system of “one entryist, one vote” made the outcome far less predictable than in any previous year.

Two contradictory things have happened in the PLP as a result of that debacle: the first, which was predictable, is that no Labour MP will ever again be persuaded to nominate anyone whom they wouldn’t support in the main contest. This is a Good Thing.
