In an interview with Germany's Der Spiegel magazine, Klaus Regling - who heads the European Stability Mechanism (ESM), Greece's largest creditor with 133 billion euros in 30-year loans already disbursed at an interest rate of 1.5 percent, is quoted as saying "there will be no debt restructuring."

In an interview to French daily "Liberation," Yannis Stournaras has expressed the hope that after four years of austerity, European partners will help Greece lower its debt so that it can be sustainable over the long term.

IMF chief Christine Lagarde denied that the Fund had erred in the time it proposed for restructuring the Greek debt, essentially refuting a report issued by the IMF at the beginning of summer, which said the decision had been delayed.
