Greek Prime Minister Alexis Tsipras warned yesterday that an insistence by European creditors on slashing pensions would scupper all hope for a default-saving agreement - and they would have to accept the burden of the consequences. "This insistence on cutting pensions is incomprehensible ... if Europe insists on this incomprehensible fixation ... it must accept the cost of a development that will benefit no one in Europe," he warned.Tsipras said he was ready to take responsibility for rejecting the terms of a deal on aid if creditors' demands were unacceptable. But the government would "bear the cost of carrying through" a viable solution.Without one, "we will assume the responsibility to say 'the big no' to a continuation of the catastrophic policies for Greece".Negotiations between Greece and its creditors are close to breakdown as Eurogroup finance ministers meet in Luxembourg today for what has been billed as a last chance to seal agreement on à7.2-billion in bailout aid.The chance is "very small" that a deal will be reached with the ministers, the group's president said. Jeroen Dijsselbloem told a Dutch parliamentary committee yesterday that the Eurogroup remained opposed to writing off Greek debt, an option considered by the International Monetary Fund.He warned that even in the case of a default, the debt "will not go away".Athens is set to default on a à1.6-billion debt repayment to the IMF on June 30 unless it receives fresh funds by then, possibly driving it towards the exit of the eurozone, but relations with its creditors are bitter. The Greek central bank warned yesterday that the country could crash out of the eurozone and even the European Union if it failed to reach a deal. ..
