Retired Lt Gen Orakzai, one of the few officers of tribal origin in the upper echelons of the Pakistani army, cited personal reasons for his departure.
But the continuing violence in tribal areas may have brought it about.
... Gen Orakzai was appointed governor of the North West Frontier Province with a mandate to improve the security situation there.
His biggest gamble was to negotiate a peace deal with local tribal leaders in September 2006, after months of bitter clashes between the army and Islamist militants that killed hundreds on both sides.
... the violence in the tribal areas continued, and that contributed to Gen Orakzai's departure.
The new governor, Owais Ahmed Ghani, has been known for his tough action - which often took the form of brutal force - against Baluch nationalists.
If his appointment indicates anything, it must be that for the Pakistani authorities, the use of force is still very much an option in dealing with militancy in the tribal areas.
- THE HAMMER IS ABOUT TO COME DOWN ON THE ANVIL.
- IT'S LONG OVERDUE.
