Which Labour faction will triumph in the deputy race?

In what may prove to be a remarkably consequential election for deputy leader of the Labour Party, there is a clear – and increasingly factional - choice between Bridget Phillipson, who was not sacked in the recent reshuffle, and Lucy Powell, who was.

In truth, having both served in Starmer's cabinet and shadow cabinet uncomplainingly for years, there's not much in strict policy terms to divide them. But that kind of thing has never stopped the Labour Party from engaging in bitter internecine disputes.

How is the Labour deputy leadership contest stacking up?

Phillipson leads on MP nominations with 175, against 117 for Powell. Bell Ribeiro-Addy, the nearest thing to a proper socialist, received just 20 and was knocked out. Also failing to reach the threshold of 80 to go to the next stage were Emily Thornberry (undecided about whom to back now), Paula Barker (pro-Powell) and Alison McGovern (supporting Phillipson).

Philipson and Powell will also need the backing of some constituency parties and unions to go through, which should prove a formality. The election will be determined by the party's roughly 300,000 members, generally to the left of the leadership and, at the moment, rather disgruntled with it.
