sp1214: Not likely. The Conservatives have been out of power for one of the longest stretches since the war. Which historically is unusual for the Conservatives. All those policies are pretty unpopular, so they won't try them.
It's pretty clear that Labour's chances of a turnaround are pretty slim. While David Cameron is a twerp, he seems to be attracting people (for some reason best known to themselves) when in any other circumstances he'd be unelectable (and could still be).
Still, 2 years is a long time. Events could turn the public Labour's way again but it's unlikely. Though not unheard of by any means.
What I'll be quite interested to see is what'll happen to Labour as a party when (if?) they loose in the next election. Will they keep the mantle of 'New Labour' or scrap it due to its rather negative association? Whatever happens, it'll be interesting, as Brown will doubtlessly be done away with.
