the party, and decided to name Déat secretary of the SFIO parliamentary group. After having been put in charge of the documentary center of the ENS by Célestin Bouglié, Déat now founded a documentary center for the SFIO deputies. Neo-Socialist period Marcel Déat published in 1930 Perspectives socialistes (Socialist Perspectives), a revisionist work closely influenced by Henri de Man's planisme. Along with over a hundred articles written in La Vie Socialiste, the review of the SFIO's right-wing, Perspective socialistes marked the shift of Déat from classical Socialism to Neosocialism. Déat replaced class struggle by collaboration of classes and national solidarity, advocated corporatism as a social organization model, replaced the notion of "Socialism" by "Anti-capitalism" and supported an authoritarian state which would plan the economy and from which parliamentarism would be repealed. During the 1932 elections, he was elected deputy of the 20th arrondissement of Paris, beating the Communist Jacques Duclos — who himself had gained the upper hand against Léon Blum in 1928 in the same electoral district. Déat and other Neosocialists were expelled from the SFIO at the 5 November 1933 Congress, for their revisionist views and disagreements with Léon Blum's policies toward Prime Minister Édouard Herriot, leader of the second Cartel des Gauches (Left-Wing Coalition). The official position of the SFIO was then to support the Cartel without participating in the government, which it considered "bourgeois." The same year, Déat joined the Socialist Party of France – Jean Jaurès Union (PSdF) created the same year by Planist and Neosocialist elements expelled by the SFIO during the 1933 Congress. The new party's slogan was "Order, Authority and Nation". The expelled faction was a minority in the SFIO, but represented the majority of the SFIO parliamentary group. They were opposed both by the left wing of the SFIO, represented by Marceau Pivert, and by the SFIO's center, headed by Blum. The Neosocialists wanted to "reinforce the state against the economic crisis", open themselves to the middle classes and participate in non-Socialist governments. Without the support of the Socialists, Déat lost his seat in the Chamber. Two years later, he joined the Socialist Republican Union (USR). He became Minister of Air in the "bourgeois" government of Albert Sarraut (Radical) but he quickly resigned his post over disputes with the Prime Minister. With the increasing threats represented by Nazi Germany, Déat wanted to maintain peace at any cost. He returned to the
