According to Information Minister Maryam Aurangzeb, Sharif also named Lt. Gen. Sahir Shamshad Mirza as the chairman of the Joint Chiefs of Staff Committee, replacing Gen. Nadeem Raza who retires this week.
President Arif Alvi later Thursday endorsed the appointments and congratulated Munir and Mirza on their promotions to four-star generals, according to a statement from the presidency.
Munir ran the Inter-Services Intelligence during Khan's term in office but was fired without an explanation from the then-premier.
Earlier Thursday, Defense Minister Khawaja Mohammad Asif told reporters that Munir's appointment was “based on merit, law and according to the constitution."
Thursday's appointments, Asif said, would “help our country and the economy to get back on the right track, as right now everything is at a standstill."
Khan's Tehreek-e-Insaf party gave a cautious welcome to the new appointment, saying in a tweet it expected the new military leadership to play its part in restoring constitutional rights and the stability of democracy.
Bajwa, in a recent televised address at an army gathering, called Khan's conspiracy allegations a “false narrative.”
“There is a limit to patience,” Bajwa said Wednesday — apparently a veiled warning toward Khan.
Alvi has hosted at least one meeting in the capital, Islamabad, between Khan and Bajwa in a failed effort to reconcile them.
In late October, Khan launched a protest march from the eastern city of Lahore toward Islamabad but stepped down from personally leading the convoy after he was wounded by a gunman who opened fire at the former premier's vehicle. One of Khan's supporters was killed and 13 were wounded in the attack. The gunman was arrested.
Since then, Khan’s protest march has moved toward Islamabad in convoys without him. However, his party announced Thursday that Khan would rejoin the march in Rawalpindi on Saturday, with tightened security. Sharif's government says it has alerted Khan's party about threats to his life.
