Asif Zardari objected to nomination of Nasir Aslam Zahid as caretaker PM because he, in past, played a role against him. Nawaz Sharif, on the other hand, accepted Najam Sethi, who in past was and continues to be, against the Sharifs and who apparently nurtures his 'Chirya' in the presidency. This is the difference between a politician and a statesman; a politician is buried in personal whims and a statesman has to overcome individualised lineages.
