Clydesdale will take up his new position in January 2006, reporting directly to Nils S Anderson, chief executive of
Carlsberg and chairman of the UK board of directors.
Clydesdale is currently managing director of brands and sales for Carlsberg UK, overseeing the on-trade and take-home sales divisions and marketing.
He joined Carlsberg in 1998 and has held a number of senior marketing and general management positions.
Fellman took over the chief executive role in August last year after the sudden departure of Colin Povey.
He said: “Doug Clydesdale has made an outstanding contribution to the development of our brands over the years and I have no doubt that he will continue to build on this track record going forward.”
