Labour leadership campaign: who might have a pop?

So there could be a Labour leadership contest coming up. Who might have a pop?

Chuka Umunna: Some members of staff in Ed Miliband’s team had concluded Chuka Umunna was worth giving serious assistance to, having concluded that their current boss was a goner a while ago. The smooth Blairite Shadow Business Secretary has also been very good at charming colleagues in the party, taking time to have coffee with those who Miliband has ignored. He believes he has the support of the party’s New Labour wing, mostly represented by Progress.

Andy Burnham: If Umunna has the Blairites sewn up, Burnham has the other side of the party. He has clearly positioned himself as a man of the left, a populist figure who sends the Labour conference to raptures. He describes himself as ‘mainstream Labour’ .
