Strictly Come Dancing lesson: Vince Cable and Ed Balls

Former Lib Dem minister Vince Cable offers a dancing lesson to Strictly Come Dancing contestant Ed Balls, who has followed him from politics to reality TV.

They joined Daily Politics presenter Jo Coburn for an impromptu lesson, where the political guests left their seats and headed to the corner of the studio.

Mr Balls is a contestant in this year's Strictly, which has just started on Saturday evenings.
