UK snack maker United Biscuits has announced that it has appointed David Fish as non-executive chairman, following the company’s decision to split the roles of chairman and chief executive.

Fish, who worked at Mars from 1974 to 2001 in a number of senior general management positions including president, Snackfoods Europe and joint president, Masterfoods Europe, is currently a non-executive director of Royal Mail Holdings, Tate and Lyle and Christian Salvesen.

Splitting the roles of chairman and chief executive will allow CEO Malcolm Ritchie to focus on daily operational duties, reported the Financial Times.
