The Speaker presides over the House's debates, determining which members may speak. The Speaker is also responsible for maintaining order during debate, and may punish members who break the rules of the House. Unlike presiding officers of legislatures in many other countries, the Speaker remains strictly non-partisan, and renounces all affiliation with his or her former political party when taking office as well as when leaving the office. The Speaker does not take part in debate or vote (except to break ties; and even then, the convention is that the speaker casts the tie-breaking vote according to Speaker Denison's rule). Aside from duties relating to presiding over the House, the Speaker also performs administrative and procedural functions, and remains a constituency Member of Parliament (MP). The Speaker has the right and obligation to reside in Speaker's House at the Palace of Westminster.
