The Chancellor's comments come after a final bid to form a government failed on Tuesday, raising the possibility of a Greek exit from the euro zone.

I want, just like Jean-Claude Juncker, that Greece stays in the euro. I think that would be good for Greece and for all of us, she said. Juncker is Luxembourg's prime minister.

Despite Merkel's comments, uncertainty loomed over Greece's economic and political future -- pushing the euro to a four-month low against the dollar.
Leaders of five political parties met in Athens on Tuesday in a last-ditch effort to form a unity government. Lawmakers, however, are bitterly divided over the austerity program the government has imposed to get huge bailout loans from the European Union and the International Monetary Fund.

Merkel, who has been a staunch advocate for budget cuts and spending reductions, is facing a growing backlash against her austerity led fiskalpact.
The election of Socialist French President François Hollande last week brought further pressure on Merkel.
Hollande, who flew to Berlin on Tuesday hours after being sworn into office, was a vocal critic of Merkel's austerity stance during his election campaign. In a meeting, both leaders pledged to forge a joint approach to boost growth in the recession-plagued region and to closely work together on resolving the sovereign debt crisis.
