Former housemate Billi has claimed that Big Brother bosses have been biased towards Charley throughout the series and that this cost him his place in the house.

The evictee also suggested that last week's Fake Week was manufactured to ensure Charley couldn't be voted out by the public.

Billi had been due to go up against Charley for the public vote, only to have his nominations taken away from him, as punishment for revealing he had voted for her.

The 25-year-old male model told The Sun: "It has become more and more obvious that I was sacrificed to keep Charley in."

He added: "Fake Week was also invented to keep Charley in. Everybody knew she'd had a really bad week and nominations were going her way."

Big Brother bosses have denied any bias, following claims that Charley has been signed up by Davina McCall's agent John Noel.

A spokesperson said: "No housemate selects an agent until they have been evicted from the house.

"No decision has been made on representation for Charley and that will not happen until she is out of the Big Brother house."
