Ed Miliband rewrote the rules of Labour’s membership, and for a long time that was held as his greatest error, destroying not just his own vision for palatable leftism but also the party he cherished. Now that Corbyn has gone from Labour’s high sparrow to its saviour, the decision to give the members real power over the leadership, power to defy the parliamentary party and laugh while doing it, is suddenly Miliband’s great legacy. In fact that decision – effectively, the party went open source – won’t mean anything unless it’s followed through. It was far more radical than anyone allowed at the time, far more meaningful than simply inviting the naive and the Trotskyists to make decisions that their youth or extremism made them unqualified to make. It opened up the possibility of politics as a co-creation, one in which the members were more than just a beard-army ready to deliver leaflets for you, then moan about your centrism in the pub.
