Stars in charity river challenge

STARS including comics Dara O’Briain and Jack Dee, actress Chelsee Healey and ex-Spice Girl Mel C are to brave crocodiles, hippos and huge rapids by tackling more than 100km of the Zambezi river.

The group will be pushed to the limit as they take on the back-breaking journey in dugout boats, canoes and white-water rafts for Comic Relief.
