Andrew makes good impression on bookies

Bookmakers have revealed that out of the three new housemates, Andrew has made the best first impression on the show.

Paddy Power has installed the maths fanatic as one of the favourites to win the series with short odds of 10/1. Liverpool cabin crew worker Rachel and travel agency manager Keeley are less well fancied with odds of 20/1 and 50/1 respectively.

Bristol sales rep Josie (15/8) remains the heavily backed favourite, but Ben (4/1), John James (6/1) and Corin (7/1) are also getting plenty of support from punters.

Dublin student Caoimhe, who Big Brother 7 star Nikki Grahame recently branded "the house bitch", is currently the longshot outsider at 50/1.
