The current policy was concocted at conference in September. Yes, it was a fudge, but it was also a genuine compromise: the leadership would have preferred maximum room for manoeuvre, but were obliged to recognise members’ desire for a second referendum; members would have preferred the demand for a second referendum not to be contingent on events, but recognised that the leadership needed room for manoeuvre. They showed discipline and restraint because they trust the leadership and because their priority is a Labour government.
This is why the poll splashed on the front page of The Guardian is not news, certainly not to members, and not to anyone who was paying attention in September.
