Being head of the state, the President of Pakistan should be non-political, non controversial and impartial. Unfortunately, PPP's candidate is as far from these standards as one can imagine. Mr Zardari and his party say about Chief Justice Ch. Iftikhar that he has been politicized and become partial and someone in his place shouldn't be so. Charity begins at home. Mr Zardari should also withdraw his candidature for presidency because that office too requires him to be impartial. -NAILA SIDDIQUI, Karachi, via e-mail, August 26.
