The Australian Labor Party (Victorian Branch) also known as Vic Labor is the Victorian branch of the Australian Labor Party. The parliamentary leader is elected from and by the members of the party caucus, comprising all party members in the Legislative Assembly and Legislative Council. The party factions have a strong influence on the election of the leader. The leader's position is dependent on the continuing support of the caucus (and party factions) and the leader may be deposed by failing to win a vote of confidence of parliamentary members. By convention, the premier sits in the Legislative Assembly, and is the leader of the party controlling a majority in that house. The party leader also typically is a member of the Assembly, though this is not a strict party constitutional require
