لون نول
On 10 March 1972, just before the newly renamed Constituent Assembly was to approve a revised constitution, Lon Nol suspended the deliberations. He then forced Cheng Heng, the head of state since Sihanouk's deposition, to surrender his authority to him. On the second anniversary of the coup, Lon Nol relinquished his authority as head of state, but retained his position as prime minister and defense minister.
