<P> The Speaker of Lok Sabha is both a member of the House and its Presiding Officer . The Speaker conducts the business in the House . He / she decides whether a bill is a money bill or not . He / she maintains discipline and decorum in the house and can punish a member for their unruly behaviour by suspending them . He / she permits the moving of various kinds of motions and resolutions like the motion of no confidence, motion of adjournment, motion of censure and calling attention notice as per the rules . The Speaker decides on the agenda to be taken up for discussion during the meeting . It is the Speaker of the Lok Sabha who presides over joint sittings called in the event of disagreement between the two Houses on a legislative measure . Following the 52nd Constitution amendment, the Speaker is vested with the power relating to the disqualification of a member of the Lok Sabha on grounds of defection . The Speaker makes obituary references in the House, formal references to important national and international events and the valedictory address at the conclusion of every Session of the Lok Sabha and also when the term of the House expires . Though a member of the House, the Speaker does not vote in the House except on those rare occasions when there is a tie at the end of a decision . Till date, the Speaker of the Lok Sabha has not been called upon to exercise this unique casting vote . While the office of Speaker is vacant due to absence / resignation / removal, the duties of the office are performed by the Deputy Speaker or, if the office of Deputy Speaker is also vacant, by such member of the House of the People as the President may appoint for the purpose . The Lok Sabha has also a separate non-elected Secretariat staff . </P> <P> Shri G.V. Mavalankar was the first Speaker of Lok Sabha (15 May 1952--27 February 1956) and Shri M.
