This website outlines the electoral system in Cambodia, and lists the contending parties.
Hun Sen's long-running control over the levers of state and his unmatchable political instincts all but ensure that he will lead a return of his party to office, with even his few serious rivals unlikely to mount a strong challenge.
Hun Sen, once a member of the ultra-leftist Khmer Rouge, has been at the helm of Cambodia since 1985, when he was made prime minister of a Communist government installed by neighboring Vietnam. He became an elected prime minister in a democratic vote only after his party won a 1998 election. His party has tightened its grip on power since then, with 73 seats in the National Assembly.
