Waitrose has axed the sale of Warburtons products from all its stores following a dispute over the quality of the popular brand.
The move comes after the premium UK supermarket claimed the bread makers' performance "didn't meet expectations", according to The Telegraph.
It means that Waitrose is currently the only major supermarket chain to not stock Warburtons products, which they have claimed to have pulled from its shelves a year ago.
The Manchester Evening News has reported the bakery chain's assertion that its "quality is paramount" and the "awful lot of care" put into its products.
A spokesperson for 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."
Waitrose countered: "At Warburtons, quality is paramount. We put an awful lot of care into the two million products we bake and deliver to over 19,000 stores across the country every single day.
"We know that consumers recognise the quality, and value of our products and that is why we are the number one bakery brand in the UK. It is a shame that Waitrose chose to delist us last year and we would of course love to be back on their shelves in the future."
The row comes after Warburtons, which is owned by the fifth generation of the Warburtons family, reportedly saw a decrease in the sale of its products last year.
The family-owned business posted pre-tax profits of £15.2m for the 12 months to September 25, 2021, compared to the £23.6m it achieved during the prior year.
However, the company also reported a turnover of £567.9m, up from £556m.
