The National Assembly nominated experienced politicians such as Sim Var and San Yun to become prime minister whenever Sihanouk took leave, but they similarly relinquished their posts each time, several months into their term, as cabinet ministers repeatedly disagreed over public policy matters.
Majelis Nasional menominasikan politikus-politikus berpengalaman seperti Sim Var dan San Yun untuk menjadi perdana menteri saat Sihanouk melepas jabatan, namun mereka sama-sama melepas jabatan mereka beberapa kali, beberapa bulan dalam masa jabatan mereka, karena menteri-menteri kabinet bersikukuh tak menyetujui materi-materi kebijakan masyarakat.
