Hun Sen rose to the premiership in January 1985 when the one-party National Assembly appointed him to succeed Chan Sy, who had died in office in December 1984. He held the position until the 1993 UN-backed elections which resulted in a hung parliament, with opposition party FUNCINPEC winning the majority of votes. Sen refused to accept the result. After negotiations with FUNCINPEC, Norodom Ranariddh and Hun Sen agreed to simultaneously serve as First and Second Prime Minister, until the coalition broke down and Sen orchestrated a coup d'état in 1997 which toppled Ranariddh. Since 1998, Hun Sen has led the CPP to consecutive and often contentious election victories, overseeing rapid economic growth and development, but also corruption, deforestation and human rights violations. In 2013, Hun Sen and the CPP were reelected with a significantly reduced majority. Allegations of voter fraud led to widespread anti-government protests. In 2018 he was elected to a sixth term in a largely unopposed poll after the dissolution of the opposition party, with the CPP winning every seat in the National Assembly. He is currently serving in his sixth term as prime minister in "de facto" one party rule.
