It is week four in The Great British Bake Off tent. Joining host Jo Brand in the An Extra Slice studio are former shadow chancellor Ed Balls, chef Monica Galetti and comedian Henning Wehn. As well as dissecting this week's goings on in the tent, Jo interviews the latest baker to leave and reveals more exclusive footage from the BBC One show. It is batter week in the tent, so Jo and her guests discuss the remaining nine bakers and their sweet and savoury creations, as well as tasting the bakes brought in by the studio audience. Plus, they look at viewers' photos of their attempts from home - the good, the bad and the downright ugly.
