I voted for Kate - seems like I am the only one at the moment!
In BB1, Craig stormed home thanks to his contribution to the "Nasty Nick" confrontation.
In BB2, Brian was funny and was entertaining, but was also quite annoying at times! He kind of won by default because he was so popular at the beginning and no one else came close ( though our Helen did have a good go!)
So in BB3 Kate really had to play the game and won when it was the most open BB yet.
