Jamie Matheson, one of Glasgow's best-known exports to the City, has retired from Brewin Dolphin after eight years as executive chairman and 40 years in stockbroking.

During his reign, private client broker Brewin's market capitalisation has more than doubled to £500 million, with funds under management rising from £15 billion to £26bn.

Mr Matheson, 59, said: "Having grown Brewin Dolphin over the last eight years, taken it through significant periods of regulatory change and completed most of the plans set out in our 2011 strategic review, it is time for me to go."

He started his career in Glasgow in 1972 with Parsons, which became Allied Provincial, moving to Bell Lawrie White in 1996. He then enjoyed a rapid rise, joining the main board in 2002 and landing the top job in 2005.

A past deacon of the Bonnetmakers and Dyers of Glasgow, Mr Matheson is already a non-executive at STV and several charities including the HMS Victory Preservation Trust.

His role will be split between Simon Miller, a non-executive for the past seven years who becomes chairman, and David Nicol, a former Morgan Stanley banker and non-executive for the last year, who becomes chief executive. Brewin is also chopping four executives from its board.

Mr Matheson said: "My final task was to arrange my own departure and replacement."
