It is the final week in the Bake Off tent and just three bakers remain. Who will be crowned this year's winner? Jo Brand hosts An Extra Slice and is joined in studio by Paul Hollywood and Mary Berry to get their take on the nerve-wracking final bakes and how and why they chose their eventual winner. Jo will interview the champion, the two runners-up and will be joined by all of this year's bakers. Plus there's lots of unseen footage from the BBC One show and a look at the best and worst viewer and audience bakes too. With everything to play for, the final three face their last ever signature to create filled iced buns, a final nail-biting technical and a classic British cake in the show-stopper - whose bakes will be deemed worthy of a champion? The Great British Bake Off: An Extra Slice - your final helping of the year.
