ATHENS, GREECE - JUNE 3:  A Greek flag billows in the wind on the Acropolis Hill on June 3, 2015, in Athens, Greece. Greek Prime Minister Alexis Tsipras is expected to be presented with the international creditors' plan of tough economic reforms for Greece in order to unlock 7.2 billion Euros of rescue loans later today. It is unclear whether Greece will accept the offer, as Tsipras has previously called for his own proposals to be considered by the creditors (Photo by Milos Bicanski/Getty Images)
