Politicians are statistically the worst performing contestants on 'Strictly Come Dancing'.

Ed Balls may be creeping closer to the ballroom and latin final after winning over the nation with his energetic routines over the past two months, but the odds of him being crowned the champion aren't in his favour as research carried out by Voucherbox.co.uk has found that members of parliament are typically not the best movers on the show.

The study - which looked into the programme's 12-year history - found the politicians average at a dismal 10th place in the competition after Ann Widdecombe - who took part in the show 2010 - and Edwina Currie, who competed in 2011, failed to impress.

While former MPs struggle with the fancy footwork, the statistics show that singers and musicians usually come out on top, achieving three overall victories since 2004.

However, it seems the show isn't following suit this year as Louise Redknapp - who was part of Eternal - is struggling to gain the judges' approval this time around.

Comedians, radio presenters and film stars are amongst the careers to have never claimed the famous glitterball trophy, while Alesha Dixon became the most successful singer in the show's history after she won in 2007 and went on to join the judging panel - replacing choreographer Arlene Phillips - for three series two years later.

Shane Forster, Voucherbox UK Country Manager said: "It is very intriguing to see that there are clear patterns in this research in terms of who is likely to be successful in this and future series. History would suggest former pop star Louise Redknapp is favourite, but with Ed Balls defying the odds each week, it could be considered anyone's game. I would not like to cha-cha-choose this year's winner!"
