Prime Minister Lucas Papademos said on Friday Greece may need a third bailout package if the austerity measures demanded by its international creditors fail to stabilize its shattered economy and restore market confidence.
It was the first time Papademos publicly confronted his people with the risk, already mooted by wary EU, IMF and German officials, that the austerity program might fall through if they don't try hard enough.
His remarks were seen as an encouragement to support pro-bailout parties in a snap election expected on May 6.
"Greece will do everything possible to make a third adjustment program unnecessary," Papademos told Italian business daily Il Sole 24 Ore, according to a transcript of his remarks. "Having said that, markets may not be accessible by Greece even if it has implemented fully all measures agreed on.
"It cannot be excluded that some financial support may be necessary, but we must try hard to avoid such an outcome."
Greece secured a 130 billion euro bailout from the International Monetary Fund and the European Union last month after it won agreement from private sector creditors to take part in the biggest debt restructuring in history.
But with its economy in the fifth year of deep recession, scepticism about the effectiveness of government reform measures and deep public resistance to further doses of austerity, there have been widespread expectations that more aid will be needed.
According to an analysis from the IMF, the EU and European Central Bank, even if Greece sticks to its agreed reform program to 2030, it may need more support after 2014.
