Parliament of Australia
Each of the two Houses elects a presiding officer. The presiding officer of the Senate is called the President; that of the House of Representatives is the Speaker. Elections for these positions are by secret ballot. Both offices are conventionally filled by members of the governing party, but the presiding officers are expected to oversee debate and enforce the rules in an impartial manner.
