General de Gaulle advocated a strong presidential government. He felt that the "regime of the parties" under the French Third Republic's system of parliamentary government (characterised by its political instability and ever-changing coalitions) was a cause of the 1940 collapse. However, the three main parties considered parliamentary democracy to be inseparable from the ideology of French republicanism. To them, de Gaulle's project appeared to be a rebirth of Bonapartism. In January 1946, de Gaulle resigned from the Cabinet.
The socialistFélix Gouin succeeded him. A first constitutional draft was approved by the National Assembly. It was supported by the Communists and the Socialists. It concentrated power in a unicameral Assembly and abolished the Senate of France. The Christian-Democrats campaigned for the "No" with de Gaulle and the opponents to a constitutional change (the classical Right and the Rally of the Republican Lefts dominated by the Radical Party).
Consequently, a new National Assembly was elected in order to elaborate a new constitutional draft. The MRP, which led the "No" coalition, became the largest party with more votes and seats than the PCF. The Communists and the Socialists no longer formed a majority, so the MRP was a necessary partner for the writing of a constitutional text. Its leader Georges Bidault took the lead role in the provisional government.
