Olympic cycling champion Victoria Pendleton, singer Michael Ball and actress Samantha Bond are among the celebrities competing in The Great Sport Relief Bake Off this month.

Judged by cookery writer Mary Berry and master baker Paul Hollywood, 16 celebrities will compete across four shows on BBC Two from 13-16 January.

The other celebrity bakers include broadcasters Emma Freud and Johnny Vaughan, Dancing On Ice judge Jason Gardiner, and actresses Jane Horrocks and Doon Mackichan.

Also taking part are Olympic champion long-jumper Greg Rutherford and former England cricket captain Michael Vaughan.

Impressionist Alistair McGowan, former Blue Peter presenter Helen Skelton, Harry Potter actress Bonnie Wright, Desert Island Discs host Kirsty Young and singers Rochelle Humes, from The Saturdays; and Jamelia complete the line-up.

The last Great Sport Relief Bake Off in 2012 was won by radio and TV presenter Anita Rani.

For the first time, a number of guest presenters will host the show in addition to regular presenter Sue Perkins.

Comedians Omid Djalili, Ed Byrne and Jo Brand will each present one episode. Brand and Byrne previously took part in The Great Comic Relief Bake Off in 2013.

Michael Ball said: "I would say that my baking ability is best described as a keen amateur, messy, somewhat over-ambitious but getting there.

"My favourite part of the day was looking into Mary Berry's eyes as she removed a metal skewer from my hand that I was sticking into a working mixer, telling me 'we don't want to have an accident now do we!'"

Helen Skelton said: "I decided to take part in the Great Sport Relief Bake Off because I'm absolutely rubbish at baking. All my friends and family laugh at anything I do in the kitchen, so I thought this might be a chance to redeem myself.

"I wished I'd practised more beforehand. When they said to me 'you've got to make a pizza' I thought they meant just put the toppings on a pizza, I didn't realise they meant make the dough and everything."

Sport Relief takes place from 21-23 March 2014.
