Prominent PPP leader and senior advocate Barrister Aitzaz Ahsan has said that Imran Khan is a national Hero and prominent leader and joining of Shah Mahmood Qureshi to his party Tehrik-e-Insaaf would benefit both. Talking to media persons at the Supreme Court building on Monday, Aitzaz Ahsan however questioned the statements by the former foreign minister against President Asif Ali Zardari that Pakistan's nuclear programme was not secure in the hands of the President. He asked Mr Qureshi why he did not utter such statements when he was foreign minister. He said now there are three major parties in the country namely the PPP, the PML-N and Tehrik-i-Insaaf and all have major weak points. He said they all should collectively work for the betterment of the country. To a question about a petition by PML-N President Nawaz Sharif in the Supreme Court against Hussain Haqqani, the former president of SCBA said that the former ambassador in addition to tendering his resignation has come to Pakistan and there should be a transparent investigation. He said the person who leveled the allegation should also be brought before the parliament. He said at present parliamentary and departmental inquiry is going on. He said the Memo should not become an issue. To another question, Aitzaz Ahsan said Supreme Court verdicts should be implemented in letter and spirit. He said implementation of some decisions of the apex court is delayed which is not the right course.
