Scottish entrepreneur Anna St Clair walked out of the Unanimous bunker in a huff because she was ineligible to win the cash jackpot.

Anna had been locked up in a dingy underground bunker along with eight other contestants until they could all reach a unanimous decision on who deserved the £1 million prize.

The group were warned before the show began that if anyone walked off before a decision was reached the prize money would automatically be halved. But Anna in typical selfish form grew sick of the experience, and as she had been outcast by the group and stood no chance of winning the money, walked off the show.

A Channel 4 source said last night: “It was incredibly selfish. Anna knew that if she walked, it would ruin the show for everyone else.

“She no longer had any chance of winning, so obviously thought it was a waste of time staying.

“Anna was not well liked by the others – she thought she was better than everyone else.

“Everyone hit the roof when she walked out as they knew their prize money was halved.”

The episode where Anna walks will be screened this Friday on Channel 4 at 8pm.
