Bookmakers William Hill have no plans to open a book on the Big Brother Golden Ticket 'controversy'.

"Scores of punters have contacted us asking to bet that it will be proved that the Golden Ticket promotion was rigged, but we have no intention of betting on the matter", said Hill's spokesman Rupert Adams.

Hill's 5th eviction betting has Lisa as the 1/16 red-hot favourite for the Big Brother boot followed by Nikki at 10/1, Imogen 14/1 and Mikey at 33/1.

Rupert Adams commented: "For the fifth week running there is an absolute certainty for who will go and punters must be rubbing their hands in glee".
