Greece needs the next instalment of international aid by Sept. 15 and is prepared to push through new austerity measures and privatisations to secure the lifeline, Reuters quoted its finance minister as saying on Tuesday. Evangelos Venizelos said financial markets were using Greece as an excuse for an attack on the euro and that whatever Athens did, markets would never be satisfied. "Everybody knows that Greece is not the problem. Greece is the excuse for an attack on the euro," Venizelos told a news conference on his return from a Eurogroup finance ministers' meeting in Brussels. -- SPA
