Gulzar Khan, a disgruntled lawmaker of Pakistan Tehreek-i-Insaf (PTI) and former bureaucrat, passed away in Peshawar on Monday.
Gulzar, who was elected an MNA from Peshawar's NA-4 constituency on a PTI ticket in the 2013 general elections, could not survive the treatment he was undergoing after suffering from a cardiac arrest a few days ago.
In a tweet, PTI chairman Imran Khan said he was "saddened" to hear about the lawmaker's death and conveyed his prayers to the grieving family.
Prior to becoming a member of the National Assembly, Gulzar had served on various prominent bureaucratic positions including deputy commissioner of Peshawar, political agent for South Waziristan and chief commissioner for Afghan refugees.
Gulzar Khan was counted among the dissident lawmakers of PTI. He had become disgruntled with the party leadership after developing differences with some ministers in Khyber Pakhtunkhwa.
During the PTI sit-in of 2014, Gulzar, like some other party dissidents, had refused to give up his NA membership.
