As in other parts of the Malaysian federation, the Westminster Parliamentary system is adopted, whereby, the leader of the party with the most seats in the state legislature would usually become the chief minister of Sabah. In other words, it is the person commanding the support of the state legislature. The chief minister is appointed by the head of state known as the Yang di-Pertua Negeri. In comparison to other states in Malaysia, the office of the chief minister of Sabah has been held by a more diverse group of people in terms of ethnicity and religion. The post has been held by Kadazan-Dusuns, Bajaus, Malays, Chinese, Muruts, Rungus, Sungai, Idaans, and other persons of mixed heritage as well as being Muslims, Buddhists and Christians.
