The Lord Speaker of the House of Lords is the presiding officer, chairman and highest authority of the House of Lords in the Parliament of the United Kingdom. The office is analogous to the Speaker of the House of Commons: the Lord Speaker is elected by the members of the House of Lords and is expected to be politically impartial.
