Butskellism
Term popularized in Great Britain during the 1950s, coined in The Economist by merging the names of two successive Chancellors of the Exchequer, Labour's Hugh Gaitskell (1950-1) and the Conservative R. A. Butler (1951-5). Both favoured a ‘mixed economy’, a strong welfare state, and Keynesian demand management designed to ensure full employment.
