PTI counsellors got kidnapped or disappeared, paving the way for ppp to claim the mayorship of Karachi.
That's the reason why i call them patloon army, never won a war, yet won every election of deep state.
If it is true PTI counselors who were forcefully detained should call for a press conference, go to court and get stay order. Request for re-election. It is just possible they did not come as they wished not to participate. Their leader also did not attend. You can not blame all petty matters to establishment, for them JI is as good as PPP to take mayorship of Karachi.
I think whatever happened was more of a doing of sindh govt aka PPP and ofcourse the provincial establishment. Cant blame army for everything
Anyway Murtaza Wahab is much better candidate than JI’s Hafiz Naeem, whose politics moves around ethnicity and hatred behaving like dysfunctional MQM of Altaf Hussain 
Amid protests, Murtaza Wahab becomes Karachi mayor
