According to the bookies, a punter has gambled £15,000 on the comic winning the series, following the double eviction of Julie Goodyear and Prince Lorenzo last night.
Clary has odds of 8/11, so the punter would take home over £25,000 if he does win.
His closest competition for the title are Martin Kemp and Coleen Nolan, who have odds of 10/3 and 7/1 respectively.
Meanwhile, The Situation is considered an outsider with 12/1 odds, ahead of Olympian Ashley Mckenzie at 20/1.
MC Harvey is thought to be out of the running with huge odds of 40/1 that he will walk away with the series crown.
