How often was then leader chosen in Cambodia?

In Cambodia, the leader is typically chosen through elections held every five years. The political landscape has been dominated by the Cambodian People's Party (CPP) since the 1990s, and Prime Minister Hun Sen has been in power since 1985. While elections are held regularly, they have faced criticism for lack of fairness and transparency, often leading to allegations of suppression of opposition. Consequently, the continuity of leadership has often favored the ruling party.
