OVER the last year, the left has seen its power in the Labour Party wane. This has been a shock to many who found their feet in party politics under Jeremy Corbyn’s leadership. But for those of us who remember the days before Corbyn, it is familiar territory. However, things have not simply reverted to how they were. We are far stronger now than in 2015. The legacy left behind by Corbyn and the organisations and networks that grew out of that period of influence are a source of hope. Momentum is the biggest of those organisations, achieving huge success over the last few years in mobilising tens of thousands of activists for the cause of socialism.
