Last October, BBH spearheaded a heavyweight marketing push designed to highlight Warburtons as ‘Britain's favourite baker' as it stepped up its battle with Premier Foods' relaunched Hovis.
The company invested £22m in the marketing push, about half of which was assigned to TV and press advertising. The ads eschewed Jonathan and Brett Warburton who appeared in previous campaigns and took a more humorous tone.
Richard Hayes, marketing director at Warburtons, said: 'Warburtons and BBH have enjoyed an excellent relationship over the past 12 years during which the agency has produced some outstanding work on our behalf.'
Ben Fennell, chief executive officer at BBH, added: 'We have huge respect for the brand, the product and the people at this extraordinary company. Although we are obviously sad that the relationship is ending, we wish them every success going forward.'
