AKIPRESS.COM - Talks on ending a deadlock between Greece and its international creditors broke up in failure on Sunday, with European leaders venting their frustration as Athens stumbled closer toward a debt default that threatens its future in the euro, reports Reuters.

European Union officials blamed the collapse on Athens, saying it had failed to offer anything new to secure the funding it needs to repay 1.6 billion euros ($1.8 billion) to the International Monetary Fund by the end of this month.

Greece retorted it was still ready to talk, but that EU and IMF officials had said they were not authorized to negotiate further. Athens insists it will never give in to demands for more pension and wage cuts.

"This is very disappointing and sad. It was a last attempt to bridge our differences but the gap is too large. One can discuss a gap, but this is an ocean," said a person who was close to the talks.

Both sides acknowledged the talks had lasted less than an hour, although even here accounts differed: Greece put the length at 45 minutes, EU officials at half an hour.

Following what it called this "last attempt" at a solution, the EU's executive Commission said euro zone finance ministers would now tackle the issue when they meet on Thursday.

With no technical deal apparently possible, the ministers are likely to have to make difficult political decisions on Greece's membership of the currency bloc.

Failure to keep Greece in the euro, after years of arduous negotiations and two emergency bailouts totaling 240 billion euros, would send it lurching into the unknown and mark a historic blow to the EU's most ambitious project.

Last Friday, Greek Prime Minister Alexis Tsipras had indicated he would accept painful compromises on demands for austerity and reform in return for debt relief.

But the Commission said after the talks, which also involved the European Central Bank, that "the Greek proposals remain incomplete".
