Relations with De Gaulle deteriorated. In January 1946, the president of the provisional government resigned in protest at the restoration of the "parties regime". The MRP ministers chose to stay in government. Nevertheless, the party called on voters to reject the proposed constitution in May 1946, fearing the election of a pro-Communist regime. After that, the MRP became the largest party in parliament after the June 1946 legislative election (28.2%) and Bidault took charge of the cabinet. In October 1946, the MRP, together with the SFIO and the PCF, presented a new proposed constitution. It was approved despite De Gaulle's call for a "no" vote. One year later, a Gaullist party was founded under the name of Rally of the French People ("Rassemblement du peuple français" or RPF).
