TV presenter Caroline Flack heads into tonight's Strictly Come Dancing final as the favourite to get her hands on the prized glitterball trophy.
The former Xtra Factor star is attracting four-figure sums with bookmaker William Hill, leading the field ahead of second most fancied Frankie Bridge, Simon Webbe and Mark Wright, who is ranked the outsider.
Flack's prospects have been boosted after she impressed even the toughest judge Craig Revel Horwood during last weekend's semi-final to claim the first perfect 40 score of the series.
The two-part finale, to be screened from 6.30pm on BBC1, will see each of the finalists take to the floor more than once. Each couple will perform a dance of the judges' choosing, and then a newly choreographed "showdance" which can blend steps from various styles.
In the second edition of the night, the fourth-placed couple, after viewer votes are counted, will be eliminated and the remaining three will run through their own favourite dance.
Although the judges' choices are yet to be announced, the showdances and favourite dances will be:
l Caroline Flack and Pasha Kovalev - showdance to Angels; favourite will be Charleston to Istanbul (Not Constantinople).
l Frankie Bridge and Kevin Clifton - showdance to Get Happy; favourite will be a West Side Story-inspired Paso Doble.
l Mark Wright and Karen Hauer - showdance to Don't Stop Me Now by Queen; favourite will be a Samba to That's The Way I Like It.
l Simon Webbe and Kristina Rihanoff - showdance to A Little Less Conversation; favourite will be an Argentine tango to Roxanne.
Also during the final will be a performance by Take That and the eliminated celebrities from earlier in the competition will return to perform a group number to a medley of songs.
William Hill said it has received bets of up to £2,000 on Flack, which had put her price way out in front at 8/13. Bridge is at 2/1, Webbe is 9/1 and Wright is a 12/1 outsider.
Hill's spokesman Rupert Adams said: "Caroline is attracting more bets than the rest of the contestants put together - but it looks very close and any of the four remaining contestants could win this."
By coincidence, the other big TV final taking place at the weekend, BBC1's finale of The Apprentice, also features a contestant called Mark Wright, who is up against Bianca Miller.
