Who presides over the joint sitting of the Lok Sabha and the Rajya Sabha ?

According to Article 108 and Article 118 of the Constitution of India, the Speaker of the Lok Sabha presides over a joint sitting of both Houses of Parliament [c3][c4][t1]. While the President of India has the authority to summon a joint sitting to resolve a legislative deadlock between the Lok Sabha and the Rajya Sabha, the President does not preside over the session [t1]. In the absence of the Speaker, the Deputy Speaker of the Lok Sabha takes the chair [c1][t5]. If the Deputy Speaker is also unavailable, the Deputy Chairman of the Rajya Sabha presides [c1][c2]. Notably, the Vice-President of India, who serves as the ex-officio Chairman of the Rajya Sabha, does not preside over joint sittings because he is not a member of either House of Parliament [c5][t4]. The proceedings are governed by the Rules of Procedure of the Lok Sabha [c1].
