Hun Sen (Khmer: ហ៊ុន សែន) (born 5 August, 1952) is the current Prime Minister of Cambodia.
He is one of the key leaders of the Cambodian People's Party (CPP), which has governed Cambodia since the Vietnamese-backed overthrow of the Khmer Rouge in 1979. He was a former Khmer Rouge who escaped to Vietnam before 1979 in order to call for the Vietnamese to overthrow the Khmer Rouge government. Since the restoration of multi-party democracy in 1993, the CPP has been in a coalition with the royalist Funcinpec party.
His current, full, honorary title is Samdach Akkak Moha Sena Padey Dekjo Hun Sen. The title "Samdech" was attached to his name in 1993 by King Norodom Sihanouk. It is only an honorary title and does not give him further powers. He has a glass eye, the result of a wound sustained during the Khmer Rouge offensive against Phnom Penh in April 1975. Hun Sen is currently the longest serving leader in South East Asia and is one of the longest serving prime ministers in the world, having been in power through various coalitions since 1985.
