The Provisional Government of the French Republic ( or GPRF) was officially created by the CNFL and succeeded it on 3 June 1944, the day before de Gaulle arrived in London from Algiers on Churchill's invitation, and three days before D-Day. Its creation marked the re-establishment of France as a republic, and the official end of Free France. Among its most immediate concerns were to ensure that France did not come under allied military administration, preserving the sovereignty of France and freeing Allied troops for fighting on the front.
