Burton's Foods, maker of biscuit brands such as Jammie Dodgers and Wagon Wheels, has announced sweeping changes to its board of directors.
Chief executive Adrian Sharp and sales director Ian Gibson have already left the company., which has begun a search for their replacements.
Finance director Steve Yarwood and Ron Southern, director of Burton's snacks business, are also due to depart shortly.
Robert Schofield has become executive chairman. He is chief executive of Premier Foods, owned by Hicks, Muse, Tate and Furst which also owns Burton's Foods, and he will retain that post.
However, Burton's Foods said there were no plans to integrate the two firms.
Daily management of Burton's Foods will be handled by Schofield and group finance director Paul Thomas until Sharp's replacement is found.
Tony Camp will remain as marketing director and John Gatfield will retain his post as operations director.
The company said its trading and marketing teams would remain in place and said customers would not experience any difference in their relationships with the business. It said all marketing and new product development initiatives would continue as planned.
Burton's Foods said the changes were not due to poor performance, adding that it had increased its share in the biscuit market during the last year.
Burton's Foods claims second place in the category, behind McVitie's and manufactures a range of own label and branded biscuits.
