Victoria is governed under the Westminster system of parliamentary government. It is a bicameral system with two elected houses. The lower house is called the Legislative Assembly and the upper house is called the Legislative Council. After an election, the State Governor appoints as Premier, the leader of the party who can control a majority of the elected members in the lower house. The Premier must resign if they no longer have a majority in the Legislative Assembly. This can happen if they lose seats at an election, or if their own political party does not support them.
