The 1972 Common Program between the Socialist Party (PS), the Communist Party (PCF) and the Left Radical Party (PRG) prepared the victory of the Left at the 1981 presidential election, during which for the first time in the Fifth Republic a left-wing candidate won. François Mitterrand, re-elected in 1988, followed a left-wing inspired social and economic program, formulated in the 110 Propositions for France electoral program. However, reforms came to a stop in 1983. Mitterrand's two terms were marked by two cohabitations, the first one in 1986–88 with Jacques Chirac as Prime minister.
