Jean Biondi

He was elected mayor of Creil in 1935 and entered the Chamber of Deputies in 1936 following a by-election in the Oise département.

He was re-elected at the general election which followed later in the year, bringing Léon Blum's Popular Front government to power.

In July 1940, he was one of the 80 who voted against the grant of special powers to Philippe Pétain and the creation of the Vichy régime.

The same year he joined the Comité d'action socialiste, the clandestine form of the then-banned SFIO.

He was elected to the National Assembly, which replaced the pre-war Chamber and the immediately post-war Consultative Assembly, serving as under-secretary to the Minister of the Interior in Léon Blum's third ministry (1946–47) and later as secretary of state under several prime ministers (1947–50), usually with responsibility for the French Civil Service .
