Legislative elections were held in France on 21 October 1945 to elect a Constituent Assembly to draft a constitution for a Fourth French Republic. 79.83% of voters participated. Women and soldiers were allowed to vote. 522 seats were elected through proportional representation.
On 21 October 1945, the French voters were called to make two choices: the election of their deputies and a referendum in order to authorize the elected National Assembly to prepare a new constitutional text. De Gaulle and the "Three parties alliance called for a "Yes" vote, whereas the Radicals and the Conservatives campaigned for a "No".
Unsurprisingly, the "Three-parties alliance" won a large majority in the National Assembly. The Radical Party, which had been the leading party of the left in the Third Republic suffered a catastrophic result, and the right was equally destroyed (because of its support of Marshal Philippe Pétain). They appeared as being the forces of the past, as symbols of capitulation to Nazi Germany and the regime which collapsed in 1940. The French Communist Party, which had already doubled its score in the previous 1936 elections, came out on top with around 26% of votes and 159 seats. While the PCF and SFIO favored a unicameral parliamentary regime, the MRP favored a bicameral legislature. De Gaulle advocated a presidential government. He resigned in January 1946. The PCF and SFIO proposals were rejected in the 5 May 1946 referendum. This assembly was dissolved.
