On 30 June 1975 Paul Biya was appointed vice president. Ahidjo resigned as president in 1982 and was constitutionally succeeded by his Prime Minister, Paul Biya, a career official. Ahidjo later regretted his choice of successors, but his supporters failed to overthrow Biya in a 1984 coup. Biya won single-candidate elections in 1983 and 1984 when the country was again named the Republic of Cameroon. Biya has remained in power, winning flawed multiparty elections in 1992, 1997, 2004 and 2011. His Cameroon People's Democratic Movement (CPDM) party holds a sizeable majority in the legislature.
