Speaker (parliament)

The speaker of a deliberative assembly, especially a legislative body, is its presiding officer, or the chair. The title was first used in 1399 in England.

The speaker's official role is to moderate debate, make rulings on procedure, announce the results of votes, and the like. The speaker decides who may speak and has the powers to discipline members who break the procedures of the chamber or house. The speaker often also represents the body in person, as the voice of the body in ceremonial and some other situations. The title was first recorded in 1377 to describe the role of Thomas de Hungerford in the Parliament of England.

By convention, speakers are normally addressed in Parliament as 'Mister Speaker', if a man, or 'Madam Speaker', if a woman. In other cultures other styles are used, mainly being equivalents of English "chairman" or "president". Many bodies also have a speaker pro tempore (or deputy speaker), designated to fill in when the speaker is not available.

The Speaker of the Australian House of Representatives is the presiding officer of the Australian House of Representatives, the lower house of the Parliament of Australia. The President of the Australian Senate is the presiding officer of the Australian Senate, the upper house of the Parliament of Australia.

Italian parliamentarism is centered on the Presidents of the two Houses, vested in defense of the members and of the assembly as a whole; so "the Speaker invites the representative of the Government not to deviate from the rules of parliamentary behavior". Now constitutional community highlights changes also in this role.
