Germany: eurozone would survive Greek exit

"The idea that we would not be able to react quickly to something unforeseen is wrong", he said. "We have learned a lot and built defences."

He said that the contagion risk for other euro countries had lessened and that the eurozone as a whole was more resilient.

"European countries and private creditors have made extraordinary moves towards Greece. We did what was possible."

His words come as the likelihood of Greece's departure from the eurozone increased after Sunday's parliamentary elections in which almost two thirds of voters chose parties that said they want to either renegotiate or scrap entirely the conditions attached to EU-IMF bailouts.

Politicians are now on their third attempt to form a government and the country may have to return to urns in June for a second election.

Time is pressing as there is an end-of-June deadline for Greece's parliament to approve a further €11.5 billion in cuts in return for the loan money.

For his part, Schauble said it was "dangerous" to allow Greek citizens to believe that there is a simpler way that avoided "hardships" to get Greece back on a healthy economic path.

Legally the exit issue is a quagmire. There are no provision for countries either leaving the single currency voluntarily or being booted out. Under EU rules, a country would normally have to leave the EU to leave the eurozone.
