THE winner of Big Brother 5 could go home empty-handed.

The 12 contestants are in for a shock when they reach the house and find the £100,000 prize money is not guaranteed.

When the series, hosted by Davina McCall, kicks off tomorrow the jackpot will be £30,000 more than in previous years. However, each Saturday the housemates will face a live challenge and failure could cost them £10,000 a task.

This means 10 disastrous performances will reduce the fund to nothing.

Last night a show source said the cash drain would give extra incentive for inmates to give 100 per cent to the tasks. She said: "They always say they are taking part in Big Brother for the experience rather than cash, but this will find out if they are being truthful.

"It's one thing to lose a challenge and miss out on a treat or two, but it's much more serious when this sort of money is involved.

"It will certainly change the dynamic in the house."

Meanwhile Playboy TV is offering £100,000 to the first couple to have sex on the show and then reenact it. The adult channel's Richard Gale said: "We think this is the year. And we want to be able to replicate the part Channel 4 won't broadcast."
