Former secretary of state at the Ministry of Environment Khieu Muth on Monday received a unanimous vote appointing him as the Senate’s newest member, filling the seat vacated at the end of April by Princess Norodom Buppha Devi. Sixty-eight parliamentarians from the ruling Cambodian People’s Party voted in Muth’s favour.

“Khieu Muth, one among the six candidates, received [a] unanimous vote today to be member of the Senate as the appointee from the National Assembly,” said assembly spokesman Leng Peng Long.

Buppha Devi – daughter of the late King Norodom Sihanouk – had served in the Senate since 2013 as one of two National Assembly appointees. Senate Secretary-General Um Sarith said Buppha Devi resigned due to a new job. She couldn’t be reached for comment.
