Irishman Brian Dowling remains the firm favourite to win Big Brother.
Paddy Power, the official bookmakers of the show,are quoting odds of 1/4 on Brian taking the £70,000 sterling prize.
A spokesman said the Rathangan man has led the way virtually from the beginning, although there seems to be a push from the programme's producers to move Helen into the spotlight and liven up the competition. She is second behind Brian at 5/2, with Dean at 50/1 and Elizabeth at 66/1.
Elizabeth is favourite to be evicted tonight at 1/5, with Dean at 3/1, Helen 33/1 and Brian at 40/1 to leave the Big Brother house.
Members of Brian's family left for London today ahead of what they hope are major celebrations tomorrow night.
A leading bookermaker in Britain hasstopped taking bets on Brian to win.
Coral Eurobet had Brian as their 1-5 favourite to take the £70,000 prize on Saturday before they closed the book.
A Coral spokesman said: "We have heard rumours that Brian is well clear on the phone vote but we finally decided to pull the plug because every Big Brother bet we were taking was for Brian."
Paddy Power are also offering a few alternative scenarios as to what the future holds for Brian once he leaves the confines of the Big Brother house.
They are offering evens on him leaving his job as a Ryanair steward and reaching for the heights of TV stardom. Or if he decides to play it safe and return to his old job, but leave before Christmas punters can try their luck at 2/1.
Alternatively, there is 4/1 on him still being with Ryanair by Christmas day; 8/1 on him leaving for another (unspecified) full-time job and the same on him becoming a spokesman for Ryanair.
