In this week's New Statesman, out this Friday, our Commons Confidential columnist Kevin Maguire hears tell in Westminster of a gathering Blairite plot to put the shadow business secretary, Chuka Umunna, in the running for the Labour leadership. Maguire learns that the necessary funds are already being arranged:

Milibandites point an accusing finger at Labour’s Progress tendency for destabilising tales of plots and supposed letters demanding the head of Ed. John Woodcock, the MP for Barrow and Furness and a former frontbencher who chairs the Blairite faction, was accused by the wobbly one’s praetorian guard of stirring the pot. The intended beneficiary, according to a well-placed snout, is the business-friendly Chuka Umunna, under the spell of Peter Mandelson. Big money is apparently lined up behind an Umunna leadership bid, whenever it comes, with the Progress sugar daddy Lord Sainsbury ready to open a fat chequebook that has been kept shut to Labour since Ed Milibrother beat David. Just because Mil the Younger is now paranoid, that doesn’t mean he isn’t aware of who is out to get him.
