RAMALLAH — The Fatah Central Committee voted unanimously this week to replace elections with a new leadership system that allocates positions based on the number of years a member has spent in Israeli prisons. "It rewards sacrifice," said a spokesman, as a recently released prisoner with a 35-year sentence was immediately appointed second-in-command, leapfrogging President Mahmoud Abbas's son Yasser, who has never been arrested. The move has prompted a wave of senior officials to frantically request their own administrative detention.
