David Cunliffe may still be Labour's leader by name. But for all intents and purposes his year-long tenure at the party's helm is as good as over ... with one reservation.
That is that he could refuse to budge and opt to exploit his support among the party's rank-and-file members and affiliated trade unions to cling on to his job.
But such a scenario is unthinkable. It would put the wider party at loggerheads with the parliamentary wing where his supporters are in the minority.
Labour is in deep enough internal strife without entertaining the possibility of outright civil war.
The depth of animosity between the pro- and anti-Cunliffe factions was evident yesterday with Cunliffe and former leader David Shearer at odds - and Shearer refusing to be silenced despite a plea from Cunliffe for his MPs to stop the infighting.
