John Mackintosh (1929-78) served as Joint Editor of Political Quarterly from 1975 to 1978, a Labour MP from 1966 to 1978, and held several academic posts, including latterly a stint as Professor of Politics at Edinburgh University. This unusual career, which spanned the worlds of practical politics and its academic analysis, gave him a unique voice in the political debates of the 1960s and 1970s. Mackintosh was a shrewd analyst of the troubled trajectory of the Labour Party, social democracy, British parliamentary government, and Scottish devolution in that period, penning many authoritative and penetrating articles on these subjects in Political Quarterly and other outlets. This virtual special issue collects together some of Mackintosh's key writings for Political Quarterly to coincide with the John Mackintosh Memorial Discussion being held in the House of Commons on 18 October.
