The NA Secretariat has issued an official notification confirming her appointment on Sunday.
The SIC had submitted the nomination papers of Zartaj Gul to the Speaker on June 21.
Earlier, the PTI had proposed four names for the parliamentary leader position, including Zartaj Gul, Sahibzada Mehboob Sultan, Zain Qureshi, and Ahmed Chattha.
However, Zartaj Gul's nomination was finally approved, solidifying her position as the parliamentary leader of the Sunni Ittehad Council in the lower house.
