Corbyn’s election as leader of Labour party in 2015 was seen by much of the British left as their best chance to reverse the neoliberal imperialist trajectory of the British state for at least a generation. With a solid track record of opposition to war, nuclear weapons and privatisation, he was able to capture the imagination of a disenfranchised youth sick of corporate-sponsored politicians, quickly turning the Labour party into the biggest mass membership party in Europe, with over half a million members. Two years later, defying all predictions, Corbyn’s Labour managed to overturn the ruling Conservatives’ parliamentary majority in a snap election which was supposed to deliver them a landslide. The prospect of a Corbyn government, with a genuine commitment to reversing the inequality and militarism that had become the hallmark of the western world, seemed to be a real prospect - perhaps even an inevitability.
Yet the general election of 2019 saw the entire project come crashing down in flames. Boris Johnson’s revitalised Tory party, united around a Brexit deal which had escaped his predecessor, stormed back to power with the party’s biggest majority since 1983, stripping Labour of dozens of working class constituencies it had held for generations. Corbyn was replaced by Sir Kier Starmer QC, heralding a purge of Corbynites from the frontbenches. Within a few months, Corbyn himself had been expelled from the parliamentary party.
