Strictly Come Dancing host Sir Bruce Forsyth strikes the famous pose of the world's fastest man.

The veteran TV host adopted Olympic champ Usain Bolt's "lightning bolt" at the recording of tonight's launch show as the BBC1 dance hit returns for its 10th series.

Sir Bruce, 84, joked that he invented signature poses by creating the "thinker" stance he used during his tenure on 1970s series the Generation Game.

Viewers will see the much-loved TV star return to helm the show once again with co-host Tess Daly as 14 new contestants start their attempt to dominate the dancefloor and waltz off with the mirrorball trophy.

The new line-up of contestants includes Olympic stars Victoria Pendleton, the gold-winning track cyclist, and Louis Smith, the silver-medallist gymnast.

Other hopefuls are actress and presenter Lisa Riley, veteran children's TV host Johnny Ball - the oldest contestant to take part in the contest - and Denise Van Outen.

Viewers will see which of the stars will be teamed with the professional dancers who once again include Brendan Cole, Anton Du Beke, Ola Jordan and Aliona Vilani who won last year's competition with her partner, McFly's Harry Judd.

The programme welcomes new judge Darcey Bussell, former principal dancer with the Royal Ballet, who replaces Alesha Dixon who quit to join the panel of Britain's Got Talent.

The show is a curtain-raiser for this year's contest proper, which begins next month, reviving the ratings battle with The X Factor.

ITV1's singing show has seen its viewer numbers falter over the past few weeks as it struggles to match the audience of recent years. Last Sunday's edition of the show brought its lowest audience since 2007, dipping below eight million.
