Former Supreme Court Bar Association’s (SCBA) president Barrister Aitzaz Ahsan on Friday said the president of Pakistan could be interrogated by the Federal Investigation Agency (FIA) in any matter, however, neither any case could be registered against him nor any prosecution could be initiated or continued against him in the court of law during his term in the office. Talking to reporters at the Supreme Court building on Friday, Aitzaz said investigation against the president could be started but no prosecution could be initiated or continued against him in the courts, as he enjoyed immunity. To a question, he said the issue of Mansoor Ijaz memo was a serious matter. He said Hussain Haqqani, who had allegedly asked a Pakistani-American businessman to assist him in privately delivering his (president’s) message to Admiral Mike Mullen, should be given chance to prove himself innocent, and if the story of the memo is wrong, Mansoor Ijaz should be punished. Aitzaz said that after the recent visit of Dr Zulfiqar Mirza to the UK and his media statements, issues had been complicated.
