who chairs the debates at the house of commons
House of Commons of the United Kingdom At the beginning of each new parliamentary term, the House of Commons elects one of its members as a presiding officer, known as the Speaker. If the incumbent Speaker seeks a new term, then the House may re-elect him or her merely by passing a motion; otherwise, a secret ballot is held. A Speaker-elect cannot take office until he or she has been approved by the Sovereign; the granting of the royal approbation, however, is a formality. The Speaker is assisted by three Deputy Speakers, the most senior of whom holds the title of Chairman of Ways and Means. The two other Deputy Speakers are known as the First and Second Deputy Chairman of Ways and Means. These titles derive from the Committee of Ways and Means, a body over which the chairman once used to preside; even though the Committee was abolished in 1967, the traditional titles of the Deputy Speakers are still retained. The Speaker and the Deputy Speakers are always members of the House of Commons.
Representative democracy It is an element of both the parliamentary and the presidential systems of government and is typically used in a lower chamber such as the House of Commons of the United Kingdom, Lok Sabha of India, and may be curtailed by constitutional constraints such as an upper chamber. It has been described by some political theorists including Robert A. Dahl, Gregory Houston and Ian Liebenberg as polyarchy.[4][5] In it the power is in the hands of the representatives who are elected by the people.
