Greek Finance Minister Yanis Varoufakis held out hope on Saturday of a last-ditch agreement with creditors to prevent Greece defaulting on its debt and sliding towards the euro exit, despite clear signs from lenders that the door was closed. "In these crucial moments, the Greek government is fighting for there to be a last minute deal by Tuesday," Varoufakis told reporters in Brussels, referring to the June 30 deadline when a 1.6 billion euro payment to the International Monetary Fund falls due.
