Greece will submit a request to the euro zone on Wednesday to extend a "loan agreement" for up to six months but EU paymaster Germany says no such deal is on offer and Athens must stick to the terms of its existing international bailout, Reuters reported. The move, confirmed by an official spokesman, is an attempt by the new leftist-led government of Prime Minister Alexis Tsipras to keep a financial lifeline for an interim period while sidestepping tough austerity conditions in the EU/IMF programme. An EU source said whether finance ministers of the 19-nation currency bloc, who rejected such ideas at a meeting on Monday, accepted the request as a basis to resume negotiations would depend on how it was formulated. A spokesman for the Eurogroup said no request had been received so far. German Finance Minister Wolfgang Schaeuble told broadcaster ZDF on Tuesday evening: "It's not about extending a credit programme but about whether this bailout programme will be fulfilled, yes or no." However, German Economy Minister Sigmar Gabriel, leader of the Social Democratic junior partners in conservative Chancellor Angela Merkel's coalition, welcomed what he called the signal from the Greek government that it was ready to negotiate.
