Lebanon's parliament speaker Nabih Berri Monday called for change to the country's confessional political system in the aftermath of the explosion at Beirut's port, blamed on official negligence and corruption. "The most dangerous thing that the port disaster revealed... is the total collapse of the political and economic system's structure," Berri said shortly after the president designated Mustapha Adib as the new prime minister. "Therefore, there must be a change to this confessional system, which is the cause of all ills." rh/ho/lg
