In academic, we say that the government remains, people running the government change. Malaysia government is HM the King, all the nine Malay Sultans and all 4 Yang Dipertua Negeri. The people running the federal and state governments change but the civil servant and civil services are neutral. They support the government of the day.That's the principle of democracy. They implement policies decided by the ruling party for the benefits of the people.
In Malaysia, people may find it hard to believe and accept because this is the first time alliance and national front parties do not rule. They have ruled since 1955. In other countries, it a normal process and part of governing.
