Greece's government Saturday struggled on in talks with lenders to secure a 130 billion euro bailout before turning to the trickier task of persuading political leaders to back the unpopular reforms involved in the rescue. On the brink of bankruptcy, Athens must wrap up talks with foreign lenders on the bailout and get political approval for it soon to ensure funds begin flowing in time for the country to pay back 14.5 billion euros of bonds falling due in mid-March. But negotiations with its ‘troika' of international lenders have stumbled over their demands that include cutting labour costs by axing holiday bonuses and lowering the minimum wage - proposals strongly opposed by Greek political party leaders. Athens failed to reach a deal with the European Union, European Central Bank and the International Monetary Fund in marathon negotiations that ended early on Saturday, with crucial issues still unresolved. “The troika is not backing down on wages, holiday bonuses and supplementary pensions,” a Greek government official said after ministers met to discuss the reforms Saturday. “None of these issues have been resolved. They are all open and the onus is on political leaders.”
