The re-election of Jeremy Corbyn as Labour leader, widely predicted though it was, has still managed to deflate moderates across the party.

Corbyn’s comfortable victory over his challenger Owen Smith (62 per cent to 38 per cent of the vote) means that, in all likelihood, he will now lead Labour into the 2020 general election – and near certain defeat.

As I wandered around the conference hotels in Liverpool, gallows humour was everywhere. It’s as good a barometer as any for the state of the modern Labour party and its descent into idiocy.
