Michelle and Emma are the overwhelming odds-on favourites for this week's mock eviction on Big Brother.

Two housemates will be voted off the show but will actually move to a secret bedsit where they will be able to spy on the housemates before returning to the house a few days later.

Michelle and Emma are 1/4 favourites to be put in the bedsit with Ahmed and either Emma or Michelle at 5/1.

Ladbrokes spokesman Warren Lush said: "Ahmed is unlikely to enter the bedsit, instead, if he doesn't quit, he is the red-hot favourite for the first proper eviction.

"We are not taking bets on him to go by his own accord as he we see it as hugely odds-on.

"The housemate who has made the biggest impression this week is Jason. From a 16/1 outsider at the start of the show he is now the 4/1 second favourite.

"When he entered the house Tarzan-style with stories about hundreds of sexual conquests we immediately wrote him off.

"Recently, however, he has established himself as a key figure in the house and could well be challenging Dan for favouritism in a matter of days."
