If PTI gains clear majority, Atif khan should be given chance for CM and Pervaiz khattak should go to national assembly. If PTI makes govt in center than Khattak should be given a federal ministry. PTI performance in national assembly has been 0/0.
However, if a coalition govt has to be formed again in KPK than Pervaiz Khattak is the only choice because other PTI leaders don't know anything about politics.
