Prime Minister George Papandreou has called for a fall referendum on "changes to the political system," including to the country's constitution. Opening a three-day parliamentary debate that will culminate in a confidence vote late Tuesday, Papandreou blames Greece's bloated state sector for bringing the country to its knees and has vowed to effect deep changes. He also says the constitutional revision will make it easier to prosecute delinquent government officials. He also says Greece is in talks for a new bailout package "roughly equal" to the first package of ¤110 billion ($155 billion) agreed to in May 2010.
