During the session, the speaker summoned Chief Whip Amir to his chamber for handing over the notification. Subsequently, he officially announced Achakzai as the leader of the opposition. It is worth noting that after the disqualification and removal of former PTI opposition leader Omar Ayub from his seat as a Member of the National Assembly, PTI founding chairman Imran Khan had proposed the name of senior politician and Tehreek-e-Tahafuz-e-Ayeen-e-Pakistan (TTAP) chief Achakzai for the position. More than 70 PTI members had signed the plea to appoint Achakzai as the leader of the opposition, a demand they had been making for a considerable time. Achakzai, a senior parliamentarian and head of his party, will now assume the constitutional role of the opposition leader in the lower house of the parliament. The position carries key responsibilities, including consultation in important state appointments and playing a central role in parliamentary oversight. The office of the leader of the opposition had remained under discussion in recent weeks amid evolving parliamentary alignments.
