From Ananova:

"The theme of the fifth series is Big Brother Gets Evil and there are some nasty surprises in store. The first evil twist is that one of the housemates will have to go without their belongings for the whole series.

The 12 will be called into the Diary Room one by one to be told only 11 suitcases are allowed into the house. They will be asked to nominate the person they feel does not deserve to get their belongings."

So they don't even compete to get their case - they have to stab each other in the back from the start!!!
