Contestant welcomes 'Strictly' dance-off

Johnny Ball has welcomed the return of the dance-off on 'Strictly Come Dancing'.

The 74-year-old TV personality believes it is "fairer" to reintroduce the stage - which sees two contestants and their partners go head-to-head in a bid to remain in the competition - to the Sunday nights results show in place of the public vote, because it will ensure "better" dancers progress to the latter stages of the competition.
