Marcel Déat was a French politician. Initially a socialist and a member of the French Section of the Workers' International (SFIO), he led a breakaway group of right-wing Neosocialists out of the SFIO in 1933. During the occupation of France by Nazi Germany, he founded the collaborationist National Popular Rally (RNP). In 1944, he became Minister of Labour and National Solidarity in Pierre Laval's government in Vichy, before escaping to the Sigmaringen enclave along with Vichy officials after the Allied landings in Normandy. Condemned in absentia for collaborationism, he died while still in hiding in Italy.

The Popular Front was an alliance of French left-wing movements, including the communist French Communist Party (PCF), the socialist French Section of the Workers' International (SFIO) and the progressive Radical-Socialist Republican Party, during the interwar period. Three months after the victory of the Spanish Popular Front, the Popular Front won the May 1936 legislative election, leading to the formation of a government first headed by SFIO leader Léon Blum and exclusively composed of republican and SFIO ministers.
