LONDON Pakistan Muslim League-N Quaid Mian Nawaz Sharif has said any conspiracy to sabotage Pakistans solidarity, sovereignty, unity and existence will be foiled with full might. Protection of lives and property of the 170 million Pakistanis must be our priority. He was talking to Members of Punjab Assembly Ali Asghar and Khurram Ejaz Chattha, who called on him at his residence to enquire after his health. Nawaz said he was striving from the very outset for the supremacy of Constitution, judiciary and parliament. He said it is the right time to stand up against all internal and external plots being hatched against the institutions. He appealed to the nation to back him strongly in strengthening federation. Nawaz underlined the need of nations unity to face challenges on internal and external fronts. He maintained that PML-N respects judiciary, legislature and executive and wants them not to cross their limits and work within their constitutional boundaries. That will help strengthen the institutions. PML-N leader said his party neither compromised on principles in past and nor it would in future. He urged the elected representatives not to leave any stone unturned in serving the nation and masses. He asked them to work day and night to lessen the hardships of ordinary man. It is their primary duty and a constitutional obligation as well, he added.
