This is a tough question. I'd really love it if Bill and Karen won, and after what happened on Saturday I'd say anything is possible. If they do a couple of reasonable-ish dances over the next couple of weeks and maintain their public support, who knows?!
More realistically though, it becomes very difficult. I think the most surprisingly strong contestant has to be Darren Gough, he has improved enormously. I really like Zoe Ball but I don't think her dancing is as good as the judges suggest (a 10 on Saturday was ridiculous). As for Colin Jackson, I think he's the best celeb dancer so far, however he's really boring and not terribly entertaining in my opinion. So it's tough! Definitely not Patsy or James though...
Tricky choice!
