Please talk with evidence. Aside from JH (who I always considered an opportunist), only Shireen Mazari and Kasuri left PTI for a while among it’s top leader only to rejoin the party later!!
True IK has dictatorial tendencies but unfortunately that is the culture prevalent in Pak politics. PML-N is Sharif brothers’ fiefdom and PPP is very much Zardari show.
Zardari showed himself to be more clever than duffer NS. He went for presidency rather than PMship. Zardari knew that even after giving up most of his executive powers to the PM, as party head, he would still be able to ‘control’ Gilani. If NS had opted to become president instead of PM and Ch. Nisar or someone-else had been appointed PM, I believe much of this post election fuss or hullaballoo could have been avoided. His intransigent behaviour and dictatorial style of rule is partly to blame for the current mess.
Furthermore military coups (I am not saying there will be a coup, I hope not) generally affect the PM directly and not the President.
