Alexis Tsipras

Crunch time for Greek state finances generated another three-way teleconference on Friday between Angela Merkel, Francoise Hollande and Greek PM Alexis Tsipras, reportedly lasting one hour.

There is a one-in-three chance of Greece leaving the eurozone this year because it may be unable to secure fresh loans and could default on debt payments, a Reuters poll showed on Thursday.

The European Union poured cold water Thursday on Greece's claims that a deal on its bailout was near, insisting that more progress was needed in talks between Athens and its creditors.

"We're not there yet. There are open issues which need to be resolved," European Commission spokeswoman Annika Breidthardt told reporters in Brussels when asked about the talks.

Greece's fourth-largest party, pro-EU To Potami, on Thursday pledged to back a new deal between the country and its creditors that could face a rocky ride through parliament.

"Whichever agreement comes to parliament, all To Potami lawmakers will vote for it, without haggling, because the country needs oxygen," party leader Stavros Theodorakis told Skai TV.

Alternate International Economic Relations Minister Euclid Tsakalotos on Thursday refuted that he spoke of a bailout program in his interview with German newspaper Frankfurter Allgemeine Zeitung (FAZ) dated May 27.

Prime Minister Alexis Tsipras said Wednesday that a deal with creditors was ?close? and government officials said an agreement was being drafted but representatives of the country?s creditors made it quite clear that they do not share such optimism.

Opposition parties urged Prime Minister Alexis Tsipras on Wednesday to seal an agreement with Greece?s lenders as soon as possible but also to inform them of what it plans to agree to.

Greeces place in the euro currency bloc looked increasingly shaky on Saturday after eurozone nations rejected a monthlong extension to its bailout program and the prime minister called for a risky popular vote on the country's financial future.

Greece remained far apart from its international creditors on a deal to unlock needed bailout aid, with the two sides unable to even agree on the amount of progress made thus far.

Greece's prime minister said Wednesday that his country is close to reaching a deal with its bailout creditors, prompting European stock markets to jump on hopes of a breakthrough in the slow-moving, often acrimonious talks.
