I'm inclined to take a dim view of this. My position is that it looks immature from a party of government to carp on about an apology that they're not going to get. But no sooner had I said this – with all the subtlety that 140 characters permits – on Twitter this weekend, than Lord Ashcroft published an eyecatching set of poll results, which included this finding:
"On the need for an apology swing voters told the focus groups that the Labour Party should say sorry for its past. They said it again and again. Members of the Labour movement were just as insistent that an apology was unnecessary. There was certainly little contrition from Ed Miliband when he accepted victory in Manchester earlier today."
