OVERNIGHT Farooq Ahmed Leghari has become the weakest president in Pakistan since Gen. Zia-ul-Haq imposed martial law in July 1977. Gone are the days when at the stroke of midnight, the president could sack the government of the day and dissolve the elected Parliament which had sent him to the Presidential House in the first place. Conceived in sin and adopted by shame, Article 58-2(b) of the Eighth Amendment of Pakistan's Constitution is now history. On April 1, the 13th Amendment passed unanimously by both Houses of Parliament took away the president's discretionary powers to dismiss an elected government and national assembly and appoint services chiefs and provincial governors.
