Stewart was born in St Andrews on 1 June 1942 and later attended University in the city before spending a year at Harvard. He returned to Scotland and became a lecturer in Political Economy in St Andrews before embarking on a political career. In 1973 he married Susie Gourlay and they had two children.
First a member of the Liberal party, Stewart was convinced by a Conservative councillor that his liberal economic views were best suited to the Conservative party, which he joined in 1967. He unsuccessfully contested Dundee East in 1970 and briefly became a councillor in London before winning East Renfrewshire in 1979. In 1983 the seat became Eastwood which Stewart held until 1997. Stewart served as a PPS in 1981 and held junior ministerial posts in the Scottish office under Thatcher and Major.
Following an incident with demonstrators in 1995 Stewart suffered a nervous breakdown, in part due to problems with alcohol. Following treatment he retired from politics in 1997, and died in December 2017.
