A fundamental flaw in UK left thinking for generations has been the abandonment of the long-term hegemonic strategy. With the election of Corbyn, a new opportunity arises for a historic re-engagement with an ambitious politics across the Left in the UK. This would, minimally, place an emphasis on long-term change. In addition, it would prioritise the focus of activism and party politics on key dynamic trajectories of the future. It must shift the terms for party politics beyond simply ‘winning state power’, and for activism beyond single issues and ethical localism towards a large-scale project to re-orient the entire platform of UK society. In so doing it should seek to transform the commonly understood ways of seeing – and feeling – what can and ought to be done. It is in the transformation of our political common sense, and the embedding of this new common sense in the UK’s institutions, which will enable the politics of Corbynism to create genuinely transformative change.
