Julian Glover thinks Gordon Brown should bow out:
There's a moment in every game when someone has to put a hand on your shoulder, whisper in your ear and tell you to walk away you've lost. Labour isn't quite at that point yet this evening but it's looking close. Tonight looks like bringing a big turnout, a sizeable Tory lead, though maybe not the large clear majority many Tories think Cameron should have won, and a big Labour defeat.
Martin Kettle's take:
Gordon Brown's acceptance speech after his win in Kirkcaldy was interpreted by the BBC studio team as practically a valedictory on his prime ministership. Maybe. My reaction was that he is keeping his options open. Brown's insistence on playing his part and on securing a stable government sounded pretty much like the words of a man who is not going to give up any time soon. The messages from Labour are that the party is in the business of trying to form a coalition if they can. Will they succeed? I doubt it. But I think Brown thinks he lives to fight another day though maybe only one more of them.
