I've sort of assumed Gordon Brown and the Labours (playing tonight at the Palladium!) will sort of default their way back in because no one really sees a better alternative rather than they're wanted --they might see some of their overall control recede.
The UK is coming out of their worst recession since World War II, and they've been the laggard of the developed world in recovering --mostly because of how dominant (for good and bad) the UK banking system has been worldwide. The good news is the financial industry bailouts in the US have actually paid off (the loans to Goldman and American Express generated over $10 billion dollars in profit for the US Treasury), and while they're taking longer, the UK banks should also rebound.
The bigger problem are all the legacy projects built by Labour since '97 to try and counterweight the loss of old manufacturing jobs after Thatcher threw them to the wolves --particularly in the north of England. A lot of those places are going to see potential cuts as the UK tries to reign in serious budget deficits --in certain cases those communities have the majority of people employed by the government and many on gov't programs, so there will be pain no matter who's in power.
[I always read the paper when I travel, and this was heavily discussed in the Financial Times the past few weekends]
EDIT: There should be bumper stickers that say "Don't blame me, I voted for Boris."
