Alone once more, Mr Corbyn wandered across to the window and gazed glumly out. How different it had all been, that joyous morning in May, just a few short months ago. The shock on the faces of those complacent so-called experts who’d dismissed him as “unelectable”. As ever, turnout among the young had towered above that of the old, giving the idealistic socialist a comfortable head start. And what fools the pollsters had been to underestimate the proportion of the electorate who worked as Marxist academics. All 12 million of them had sent Mr Corbyn on his way to an extraordinary landslide victory.
