The government was headed by Sihanouk as
head of state. The Prime Minister was lawyer and veteran centrist politician
Penn Nouth, Sihanouk's political adviser, who had several times served in this capacity both under
the French colonial regime and as part of the
Sangkum. Khieu Samphan – who remained within the "liberated areas" of Cambodia, allowing the GRUNK to claim not to be a government-in-exile – was deputy premier, minister of defense, and chief of the GRUNK's armed forces. Hou Yuon, a popular and relatively liberal figure amongst the communists, was given several portfolios including that of minister for cooperatives, while Hu Nim was Minister of Information. Nouth, Samphan, Yuon and Nim were all men with a high profile and levels of popularity amongst the Cambodian populace, particularly the latter two, who had often spoken in favour of the rights of the rural peasantry. Command of the military was however in reality in the hands of
Saloth Sar, whose presence in the senior levels of the Khmer Rouge (along with
Nuon Chea,
Son Sen and
Ieng Sary) was kept essentially secret. The Front's military forces on the field, the Cambodian People's National Liberation Armed Forces (CPNLAF) were initially small, and most of the early fighting in the
Cambodian Civil War was in fact carried out by North Vietnamese forces with CPNLAF assistance. Sihanouk's relationship with the Khmer Rouge leadership was always rather strained. While Yuon, Nim, and Samphan had a long experience of being castigated and humiliated by Sihanouk during their years as
Sangkum deputies and earlier, Sihanouk had a particular personal dislike for Ieng Sary, who in 1971 was assigned from
Hanoi with the express mission of keeping Sihanouk under control. Sihanouk repeatedly (and quite incorrectly) accused him of being a North Vietnamese agent, and forced Sary to sit through risqué films obtained from the French embassy, revelling in his obvious discomfort. Sary, for his part, attempted to spread dissent in the royal entourage, and between Sihanouk and Penn Nouth. ==Takeover by Khmer Rouge==
