It is the semi-finals in the Great British Bake Off tent, where the remaining four bakers go head to head for a place in the final week. Jo Brand hosts An Extra Slice and is joined by three celebrity Bake Off fans, including reigning Bake Off champion Nadiya Hussain and leader of the Scottish Conservative & Unionist Party Ruth Davidson. As well as dissecting the goings-on in the tent, when the bakers tackled patisserie, there is more unseen footage from the BBC One show, a chance to taste bakes brought in by the studio audience and look at photos of bakes from viewers at home - the stonkers and the stinkers. Plus, Jo interviews the last baker to leave before the final. What do the panel think of the bakers' signature French pastry? Who do they think rose to Paul's yeast-based fruit and chocolate cake in the technical? Whose showstopping mini cake bake won the day? And which baker will the panel tip to be crowned the Great British Bake Off Champion 2016?
