no chance unless nawaz sharif shows signs of weakness. punjabis always support the strong guy irrespective of right/wrong or even loyalty. if today raheel shareef decides to kick out nawaz sharif forget public, 80% of all pmln mna's will support raheel shareef.
However, i do think that things nawaz sharif gets away with, no other party would be allowed to get away with them. for eg, if PPP or PTI
1) had killed 14 people in model town on live TV
2) passed women rights bill
3) hanged qadri
they would have been crucified by now. You would have seen all opposition parties start country wide movement against pti/ppp by now and nawaz gannjjuu would be leading the alliance. Thank god IK is not such an opportunist and he stands by what he believes. Otherwise he could easily join these protests to overthrow nangi league.
