Why did Charles de Gaulle oppose the constitution of the Fourth Republic?

Charles de Gaulle opposed the constitution of the Fourth Republic primarily because he believed the proposed system was unworkable and lacked the necessary stability provided by a strong executive branch.1

While the political elite of the era were divided—with some, particularly the Communists, favoring a system that concentrated power within a one-house legislature—de Gaulle consistently advocated for a strong presidency. He viewed the assembly's constitutional drafts as inadequate and actively campaigned against them, arguing that France required a more robust executive authority. His vision for a stronger presidency eventually served as the foundation for the Fifth Republic, which he helped establish in 1958.12
