David Shearer's new chief of staff, Fran Mold, has three months at most to resuscitate his flagging leadership of the Labour Party.
If his and Labour's opinion poll ratings are still in the doldrums come the party's annual conference in early November and remain there ahead of the Christchurch East byelection shortly afterwards, then it is odds on Shearer is a goner.
While there may yet be no consensus on who should replace him, the factions in the Labour caucus will ultimately do a deal which ensures there is just one candidate for leader - thus avoiding the distraction of a party-wide leadership election required under Labour's new rules and which could take weeks.
The lack of an obvious successor may be saving Shearer's bacon right now. But that is not a sustainable reason for keeping him in the job.
The return of Mold, his former chief press secretary, should bring some much-needed direction to Shearer's parliamentary office which insiders say is lacking in the political expertise that a leader lacking in experience so desperately needs.
