We can argue how big a mandate was given, and but that is not the point. The support to form a government comes from people, not from clutches of MQM, PML (Q), or XYZ, with few seats. Has PTI shown better performance then none of these blackmailers could have twisted its arm for their personal gains?
Hike in food prices, as well as shortages, has nothing to do with IMF, rather sheer incompetence. If they have anything to do with IMF then they would stay at a certain level - will not go up and down like a yoyo.
Don't mingle things up. If three LNG ships were cancelled by someone incompetence then don't try to relate that to past incompetent and corrupt governments. People were hoping a change - for the better (not the same or worse) !
