The Speaker is second in the Sierra prime ministerial line of succession, after the Deputy Prime Minister, and ahead of the President pro tempore of the Senate. As presiding officer, the Speaker may choose who may speak during the debate, set up rules for the debate, maintain order, enact disciplinary action, and tally votes. In addition to their role as presiding officer, the Speaker functions as the leader of their party, and sets its legislative agenda. As the chair of the House Committee on Procedure, Rules, and Administration, the Speaker oversees which bill may pass to the floor, and the procedures to voting on said bill. The Speaker does not always preside over debates, and in their absence, they appoint a Speaker pro tempore from their party to assume that duty.
