Celebrities, chefs and politicians share their favourite bakes to raise money for the Ben Kinsella Trust, which raises awareness about the growing problem of knife crime. There's a long list of famous contributors, here's a small sample: Jamie Oliver, Barbara Windsor, Michel Roux Jr, Gareth Malone, Sam Cam, Leona Lewis, Joanna Lumley, Nigella Lawson... The book will be launched at the Cake & Bake Show in Earls Court in September and there's a foreword by Mary Berry.
