Speaking seriously now, labour should go for someone with a good presence who can communicate flawlessly. Its going to be all new next time around, so experience etc will be irrelevant.
I think all the names mentioned have history, and that's never a good thing. Start with a clean slate, and focus on policies that engage a larger cross section of the electorate and labour will be in a much better position to engage in a federal UK. They will of course need someone for Scotland too - good luck with that
