In a fallout from the appointment of Lt Gen Raheel Sharif as the new Army chief,Lt Gen Haroon Aslam Thursday resigned because he was superseded for the top post.
Lt Gen Aslam was superseded by Lt Gen Sharif and Lt Gen Rashad Mahmood,who was made the Chairman Joint Chief of Staff Committee.
Aslam sent his resignation letter to the Defence Ministry from the General Headquarters,an official said.
PM Nawaz Sharif had earlier said he would go by seniority to select Army chief,but Wednesday chose the third senior ranking General.
Analysts said Aslams resignation was on the cards. Some felt Lt Gen Mahmoods appointment is an attempt by Sharif to sideline Gen Ashfaq Parvez Kayanis preferred candidate and reassert his authority over the military.
