Charley is the red hot favourite to get the boot in Friday’s eviction and bookies believe she’s set to be the most unpopular housemate ever.

The London It Girl is a 1/500 chance to be leaving Big Brother for good this time, following her fake eviction two weeks ago.

And the mouthy 22-year-old is odds-on at 1/2 to break Sezer’s record – 91.6 per cent of total vote – to become the most unpopular housemate in the show’s history.

Charley clearly needs a miracle to survive eviction again, as her fellow nominee Tracey is at 16/1 to go.

Ladbrokes spokesman David Williams said: “If Charley survives it’ll be the biggest upset in Big Brother betting history.

“The gobby witch is picking fights with Chanelle just when Chanelle is getting more popular with punters. Charley’s lack of judgment knows no bounds and the trapdoor is wide open.”

Brian remains the bookies’ 4/7 favourite to win the show although Charley’s departure is likely to be great news for rival Chanelle who continues her climb up the betting.

“At last Chanelle will be able to enjoy herself fully. Punters have warmed to her recently and we’re expecting her to shine from now on,” David added.
