Yes. I was willing to let him adjust to the position, but it's just been one mistake after another. The problem is that, knowing how the advisers & subordinates etc work in Pakistan, he's succumbing to the sycophancy of those around him. That sycophantic behavior is not going to change, which is why leadership capable of understanding sycophancy, and rejecting advice that leads to actions with bad optics, is necessary.
I personally feel that Buzdar is 'clean' and 'genuine', but he's in the swamp of Pakistani politics and bureaucracy, and it is his 'innocence' and lack of street smarts that are becoming his undoing.
No. The CM is elected by the Provincial Assembly. The CM can either resign or be voted out under a no confidence motion in the provincial assembly. Given Pakistan's style of politics though, Imran Khan can ask him to resign and Buzdar will most likely comply.
The problem then becomes of the ensuing internal PTI power struggle and who the next candidates will be, and given that the Punjab government is a coalition that includes the PML-Q, it is not going to be pretty.
He really needs to consult with the PTI leadership before making statements. There is nothing wrong with saying, "We're still looking into this development and will issue a statement as soon as we have details".
