It looks as though the fake eviction on Big Brother this week is going to be a close-fought battle – if the latest odds are anything to go by.

According to bookmakers Paddy Power, Charley is the hot favourite to be voted out, with odds of 1-3, but fellow nominee Nicky is at 2-1.

Unbeknown to the housemates, Friday’s eviction is a fake one. Whichever housemate is given the boot will leave the house, be interviewed by Davina, and then sent straight back in.

In a further twist, the housemates will have been shown the eviction interview, and will know exactly what the evictee has said about them.

Meanwhile, Charley’s odds on winning the series have shortened to 25-1, after weeks of being the rank outsider. Nicky is now the outsider for victory at 50-1.

Brian is the favourite to win at 13-8, followed by Liam at 3-1, Amanda at 11-2, and Gerry at 13-2. Amanda is proving far more popular than her twin Sam, who is 14-1.

Paddy Power are also offering odds of 10-1 on a new housemate coming in and snatching victory from the other housemates.
