Waitrose has removed all Warburtons products from its shelves, according to reports. The supermarket, which is part of the John Lewis Partnership, has been reported in The Telegraph as saying the crumpet maker's "performance didn’t meet expectations".
Warburtons has countered that "quality is paramount" and that it has put "an awful lot of care" into the products its bakes.
Waitrose said: "We stopped selling Warburtons products a year ago after their performance didn’t meet our expectations. We focus on fantastic products at great value that our customers love and we remain open to working with Warburtons in the future."
