Greek president set to appoint caretaker government

Final talks to form a coalition failed on Tuesday, raising new concerns over Greece's eurozone future. "There has been deadlock since the May 6th election over whether to continue with the austerity measures required by an international bailout agreement. The uncertainty pushed the euro to a new four-month low against the dollar.European Union officials fear Greece will elect an anti-bailout government, which could trigger a Greek exit from the euro. That possibility is now discussed openly among Europe's leaders," the BBC's Mark Lowen in Athens says.

But a senior adviser to European Council president, Herman Van Rompuy played down that possibility on Wednesday."We're not planning for a Greek exit, nobody is planning for a Greek exit," Richard Corbett told BBC Radio 4's Today programme.
