Explanation:

Speaker of Lok Sabha

The Constitution of India provides for joint sittings of both the Houses to break in the case of a deadlock between the two houses of parliament. The joint sitting of the Parliament is called by the President and is presided over by the Speaker or, in his absence, by the Deputy Speaker of the Lok Sabha or in his absence, the Deputy-Chairman of the Rajya Sabha. If any of the above officers are not present than any other member of the Parliament can preside by consensus of both the House.
