While none of the housemates could ever claim to be model citizens, Big Brother's Seven Deadly Sins Task looks set to divide the House.

One housemate will be called to the Diary Room where they will find seven 'Sin Bins', representing sloth, gluttony, greed, pride, lust, envy and wrath. Using cut-out faces, the housemate must choose which fellow housemate is most guilty of each sin.

Big Brother will then test the housemates on how sinful they are. If housemates prove themselves to be saintly and pass the task, they will receive a luxury food budget for all. If they fail, there'll be hell to pay...

The housemate called to the Diary Room must not reveal their part in the scheme - let slip and automatic failure will be the payoff.

Exactly who will cast the first stone is unclear but come back later to see if it will be an eye for an eye...
