The Week: Advertising news - Ryvita sticks with Britton

Ryvita has said it will stand by its brand ambassador Fern Britton, who this week admitted to having a gastric band operation despite long maintaining that her weight loss had come as a result of healthy eating and exercise. Britton has appeared in Ryvita's advertising for the past four years, including a tongue-in-cheek campaign for Ryvita Minis that saw her head superimposed on the body of a thinner woman.
