The Great Sport Relief Bake Off

It is Ed Byrne's turn to take up the baking baton and support the four celebrities as they face their three challenges in the Bake Off tent.

The bakers on the starting line are impressionist Alistair McGowan,Saturdays singer Rochelle Humes, comedian Doon Mackichan and former Blue Peter presenter Helen Skelton, who rowed the Amazon and trekked to the South Pole for Sport Relief. Will her baking prove as much of an ordeal?

The bakers must make pizzas for their signature challenge, eccles cakes in the technical challenge and showstopping tiered cakes that represent sporting equipment.

While the bakers aim to inspire others to raise money, Olympic gold-medallist Nicola Adams visits South Africa to see first-hand how your money is making a difference to those who really need it. She meets Queen, a 14-year-old girl who has been orphaned and must now look after her younger brother. Nicola meets the people who help give Queen, and so many others, the chance to be free to be children again, if only for short breaks within their week. Your money really does make a difference.
