The four finalists step onto the floor for the last time tonight as ballroom show Strictly Come Dancing crowns its 2012 winner.

Olympic gymnast Louis Smith is the bookmakers' favourite to win the glitterball trophy ahead of Girls Aloud star Kimberley Walsh, TV presenter Denise van Outen and actress Dani Harmer.

Smith won a silver medal for his pommel horse routine at the Olympics and after a shaky start in the show, the 23-year-old has wowed judges.

All four finalists will perform two dances, with one couple then voted out. The three remaining pairs will then perform their favourite dance from the series before the glitterball trophy is handed to the victor.

Walsh, who has previously scored a perfect 40 with her dance partner Pasha Kovalev, had to take her Strictly dance partner to a film shoot with her Girls Aloud bandmates to squeeze in an extra rehearsal.

Van Outen and her dancing partner James Jordan are favourites to go out first. Despite impressing the judges, their performances have not attracted the support of viewers and they have been in the dance-off two weeks running.

Another of the stars of this year's series has been former prima ballerina Darcey Bussell, who has confirmed she will return as a judge next year.

The grand final is at 6.30pm, with the results show at 8.50pm.
