This evening is the final night for this year’s Big Brother and as it stands William Hill rate Sam as their hot favourite at 8/11, with Dexter 9/4 and Gina 4/1.
“Sam is the obvious favourite but Dexter obviously has a following outside the house and we might just see an upset,” said William Hill spokesman Rupert Adams.
However, after Saturday night’s show William Hill saw a few big bets for Gina, including a £500 wager, but Sam is still tipped to triumph.
“The final of Big Brother is always the biggest turnover night of the series and tens of thousands of pounds will change hands on Monday evening!” Adams added.
Our final popularity poll predicts a very close vote, with fewer than 3% splitting Sam, Dexter and Gina at the top of the votes.
Currently it's Sam that leads the way with Dexter in second spot, but any of the trio could ultimately win come this evening.
