Saira is topping most polls, polls are not always right but they do tend to be a good indication of whos in the bottom 2, and its not Saira, the loose women vote has been strong in previous series so i see no reason why it would not be this week. i actually think Saira is probably topping the official vote , despite what the bookies odds are.
I think Lewis is going i really cannot see any other outcome, unless Heavy D goes, again i find this unlikely though.
