Medal-winning gymnast Louis Smith is to take on another TV challenge by teaming up with fellow Olympian Greg Rutherford on Channel 4’s The Million Pound Drop.

Louis – who is to be seen taking to the floor on BBC One’s Strictly Come Dancing on Saturday – and gold-winning long-jumper Greg will be guest contestants in the new series.

The high-stakes programme returns on Friday night with Alex Brooker and Josh Widdicombe, known to viewers for appearing on C4’s comedy show The Last Leg, lined up as contestants raising money for Paralympic charities.

The channel said that its recent charity version of Million Pound Drop, featuring names such as Vic Reeves, Professor Green, Countdown’s Rachel Riley and Jedward, had raised a total of 700,000 pounds.

It will be split between 14 different Paralympic and disability charities – including British Blind Sport, the British Paralympic Association and the Riding for the Disabled Association – with each receiving 50,000 pounds.

Syeda Irtizaali, C4’s entertainment commissioning editor, said: “We included a number of charities that don’t get quite as much attention so the money raised would really make a difference.”
