A day ahead of a crucial emergency eurozone summit, Greek Prime Minister Alexis Tsipras has presented a new proposal in calls to French President Francois Hollande, German Chancellor Angela Merkel and European Commission President Jean-Claude Juncker.

A government source close to the talks says Tsipras "presented to the three leaders Greece's proposal for a mutually beneficial agreement, which will provide a permanent solution and not just postpone tackling the problem." The source is not authorized to be named in the media.

Tsipras has been meeting with his senior ministers all day and will leave for Brussels later Sunday.

The governing Syriza party is holding an Athens rally later Sunday in support of the government — that comes after a strong rally Thursday of those favoring a deal with the EU.
