Michelle Bass is favourite to leave the house

Michelle Bass is favourite to leave, with bookmakers confident her possessive behaviour towards Stuart Wilson has turned viewers off.

Her patience was tested when her boyfriend was shackled to Shell Jubin for this week's TV task.

Jason Cowen, 30, had been favourite for eviction at the start of the week.

Michelle this week threatened in jest to attack Stuart's friends if they introduced him to any women outside the Big Brother house.

Her odds of being evicted have been slashed from 4/7 to 1/6 on while bookies say that Jason's chances of staying are growing all the time.

'Too obsessive'

This week he made it clear to the other housemates that he preferred his own company following last week's eviction of Victor Ebuwa.

Ladbrokes spokesman Warren Lush said Michelle was "certain to walk".

Nadia is the bookmakers' favourite to win

He said: "Michelle has sealed her own fate. Less obsessing over Stu could have saved her.

"Jason is very lucky as he should be gone."

The housemates had different theories about the eviction night as they enjoyed a barbecue dinner on Thursday night.

Shell suggested that it would be the last night in the house for all of the contestants with Stuart and Jason agreeing.

Nadia Almada remains 1/4 favourite with bookmakers to win the series.
