A TV and newspaper pundit whose views on Scottish football and politics have roused vast armies of both admirers and detractors.
A former footballer, Stewart spent seven years at Manchester United under Sir Alex Ferguson, before going on to play for both Hearts and Hibs.
His most recent career as a BBC football pundit has given him a fresh profile as a sharp and articulate opinion-maker.
Stewart is politically active and is a member of the SNP. He is an avowed believer in independence for Scotland and will hardly let up on the subject.
