Long-serving Cambodian prime minister Hun Sen has been voted in for another five years.
Members of the ruling party voted to extend Hen’s term, who has been in charge since 1985.
But it comes amid protests from the main opposition party, who claim it won July’s general election.
The Cambodia National Rescue Party (CNRP) boycotted the vote to re-install Sen.
Sen said CNRP had not pressed its demand for an independent inquiry into alleged irregularities during the July poll.
Sen, 61, has been in power for 28 years and has said he will rule Cambodia into his seventies. He portrays himself as the man who saved Cambodia from the terror and chaos of the Khmer Rouge years in the 1970s and the civil war that followed.
