Greece's second bailout package, which was agreed on July 21 and involved private sector bondholders, is under review with authorities considering increasing the losses that private creditors will incur, euro zone officials said.
"We are negotiating in every way to lighten this debt. This is the big negotiation and this is where the big problem lies," Papandreou told a cabinet meeting, without providing any details.
Papandreou told ministers the euro zone and the Group of 20 major economies need to provide persuasive and courageous responses to the debt crisis at summits later this month and in early November.
