Strictly judges take to the floor

Newcomer Darcey Bussell adds some sparkle to the Strictly Come Dancing panel as she joins her fellow judges for a spin round the floor - in a mirrored, glitterball-style dress.

All four judges will be seen dancing together in a new trailer as a taster for the forthcoming series in which Bussell replaces Alesha Dixon.

Len Goodman, Craig Revel Horwood and Bruno Tonioli battle over who can perform the slinkiest moves as they vie for a turn with their new colleague in the BBC One teaser.

The quartet filmed the routine, choreographed by Craig, at a glamorous country retreat and it is the first time since the launch of Strictly that all the judges have been seen dancing together.

The series returns to BBC One on September 15 when viewers will see the contestants team up with their partners for the first time.

Contestants include former children's TV presenter Johnny Ball - the oldest-ever entrant at 74 - and former England cricket captain Michael Vaughan. Others reportedly taking part are Girls Aloud and Shrek The Musical star Kimberley Walsh and Jerry Hall.

Alesha bowed out of the show earlier this year to be a panellist on Britain's Got Talent on ITV.
