Four more celebrities head to the famous Bake Off tent in aid of UK fundraising event, Sport Relief. Judges Mary Berry and Paul Hollywood set three tasks to test each celebrity's baking prowess, while comedian Sarah Millican is on hand to guide them through.

The celebrities taking up the baking baton this time are actor Alison Steadman, comedian Ade Edmondson, singer Will Young and actor and comedian Morgana Robinson.

The signature challenge is to create an open-top pie. For the technical challenge they attempt a salmon roulade. Finally they must make a showstopping creation depicting a momentous life experience - in cupcakes!

Which of the bakes will measure up to the exacting standards of the judges and win them the coveted Star Baker apron?

While the celebrity bakers hope to inspire others to get involved in fundraising for Sport Relief, Clare Balding visits Kenya to learn about the work of Sport Relief there. She visits a project that helps to change the lives of disabled children living in Africa. Show less
