I've said it before and I'll say it again: those who "call for unity" in the party are invariably people who are essentially telling the left of the party to shut up and go away. Well that is not going to happen. The real splitters in the party are the Blair/Brown ex-acolytes and their descendants who forgot long ago that Labour was founded as a party for the working classes and trade unionists, not as the conscience-ridden arm of the establishment. Instead, they revelled in the "glory years" of Blair and ignored the inconvenient fact that the gap between rich and poor grew faster in that 13 years than it ever does under the Tories. Jeremy Corbyn was demonised because he hadn't forgotten what Labour is for. This morning we had Mandelson, that yesterday's man par excellence, on the radio spitting out bile about Corbynists. Even though we won the bloody by-election, he simply couldn't help himself, could he. And before the result was known, the chatter was about who would take over from Starmer once he'd been booted. Guess what: the best they came up with was Yvette Cooper. Yvette bloody Cooper. A disaster waiting to happen.
