Current odds from Ladbrokes on some likely challengers to Corbyn:
Dan Jarvis 5/1
Tom Watson 5/1
John McDonnell 6/1 (said he will only stand in the event that Corbyn doesn't)
Lisa Nandy 10/1
Chuka Umunna 12/1
Angela Eagle 14/1
Owen Smith 20/1
Heidi Alexander 25/1
Yvette Cooper 33/1
None of the above look any more electable as Prime Minister than Corbyn to me. Three of them I've never heard of.
Interesting that Hilary Benn isn't on the shortlist - he has previously indicated he doesn't want to be leader, but he was generally regarded as fairly centrist (and perhaps had the name to pick up some of the left), is a very good parliamentary performer whose stock went up after his Syria speech (though that might have turned some people off), and has a reputation for being a conviction politician.
Dan Jarvis is most likely to pick up wavering Tory voters, but is maybe too green; Watson is surely too linked to Brown; McDonnell is a better performer version of Corbyn; Nandy, Smith and Alexander aren't well known enough, though Alexander is quite good on the floor of the House; Umunna could probably win if he runs, but there are questions over that; Cooper is too tied to Ed Balls, perhaps, though 33-1 seems long.
Eagle isn't popular (though does have the best bad taste nickname in politics, bestowed on her by a gay Tory activist friend of mine: the lezzer of two Eagles).
