The arrival of the three new housemates has really shaken up the Big Brother house, perhaps more than the producers could have even imagined.
Even though neither Pav nor Zoe really seem to have much chance of winning, their mere presence is looking set to have a big impact on who eventually does.
Chris has seen the biggest change in odds, now at 12/1 from one of the favourites at 5/1, according to Boylesports. It seems his attempt to steer Pav clear of Ashleigh did not go down well with the public.
Meanwhile, Mark is another housemate on the move who is now also at 12/1 having been one of the firm favourites both inside and outside the house for weeks. After being on the receiving end of some harsh words from ‘love interest’ Mark, there's better news for Christopher who is now the 9/4 second favourite to win
Ashleigh’s growing popularity has seen her receive a surge of support and she is holding her own at the top of the betting as the 11/10 favourite.
Pop Idol's Zoe has been constantly drifting and is now out to 20/1. Helen and Ash both remain at 28/1 whilst Pav, who has been shunned from the group, is sitting at the bottom of the betting at 100/1.
Aoife Heffron of Boylesports said: “Chris has been pushed out to 12/1 from 5/1 to win following his strange obsession with newbie Pav. Chris had the potential to win having been the one time favourite but it seems he is not dealing with the newcomers very well and may have ruined his chances”
She added: “Another housemate who may have shot themselves in the foot is Mark who has become increasingly argumentative and has lost that sparkle that made the public love him in the first place. At 12/1 it is hard to see him climb back up the betting stakes”
