Greece and its EU-IMF creditors prepared to submit rival proposals to end a five-month debt row, indicating there was still no deal ahead of a meeting of eurozone finance ministers on Thursday, sources said.

"There is a set of documents unanimously agreed by the (creditor) institutions that has now gone to the Eurogroup and can be the basis for a deal," an EU official told AFP minutes before the ministerial talks, the fourth meeting in a week.

A Greek official said separately: "Our proposals were detailed and will be presented to the Eurogroup."
