On 14 June 1993, Sihanouk was reinstated as the head of state in a constituent assembly session presided over by Ranariddh, who took the opportunity to declare the 1970 "coup d'état" which overthrew Sihanouk as "illegal". As Head of State, Sihanouk renamed the Cambodian military to its pre-1970 namesake, the Royal Cambodian Armed Forces. He also issued orders to officially rename the country from the State of Cambodia to simply "Cambodia", reinstating "Nokor Reach" as the National Anthem of Cambodia with some minor modifications to its lyrics, and the Cambodian flag to its pre-1970 design. At the same time, Sihanouk appointed Ranariddh and Hun Sen co-prime ministers, with equal powers. This arrangement, which was provisional, was ratified by the Constituent Assembly on 2 July 1993. On 30 August 1993, Ranariddh and Hun Sen met with Sihanouk and presented two draft constitutions, one of them stipulating a constitutional monarchy headed by a king, and another a republic led by a head of state. Sihanouk opted for the draft stipulating Cambodia a constitutional monarchy, which was ratified by the constituent assembly on 21 September 1993.
