Sue Perkins hands over the baton to Jo Brand to support the next four celebrity bakers through their three Sport Relief challenges. This time the battle is between Desert Island Discs' Kirsty Young, singer and actress Jane Horrocks, Olympic gold-medal winning long jumper Greg Rutherford and ice skating's Mr Nasty, Jason Gardiner.

For the signature challenge Mary Berry and Paul Hollywood have set gingerbread biscuits, for the technical a banoffee pie and for the showstopper a representation of their jobs - in cake. From Kirsty's 'Dessert Island Dish' cake to Greg's sponge sandpit, who will impress and be the one to win the Sport Relief Star Baker apron?

They are baking in the tent to raise money for Sport Relief, and Olympian Nicola Adams travels to South Africa to meet some of the most vulnerable people who your money can help. She meets Mamjiji, a young boy who has been living on the streets of Durban and facing the danger and stigma that goes with it, until he joined a project that gives him a temporary home and teaches him to surf, giving him an identity that he can be proud of.
