The Social and Radical Left (French: Gauche sociale et radicale, GSR) was a parliamentary group in the Chamber of Deputies of France during the French Third Republic founded in 1928 by Henry Franklin-Bouillon. The Social-Radicals or Social-Unionists were members of the right-wing of the Radical-Socialist Party who refused a new Cartel des Gauches and supported the conservative coalition led by Raymond Poincaré. Most later became members of the Independent Radicals (PRI) or even the centre-right Democratic Republican Alliance.
