The European Commission said on Monday it expects the next Greek government to respect the terms of a financial rescue after the rise of anti-bailout parties at weekend elections.

"The Commission hopes and expects that the future government of Greece will respect the engagements that Greece has entered into," commission spokeswoman Pia Ahrenkilde Hansen told a news briefing.

Greek conservative leader Antonis Samaras, whose party came on top of Sunday's elections, said he would seek to "amend" the country's controversial EU-IMF loan agreement in order to boost growth.

But the conservatives and Greece's other mainstream party, the Socialists, fell short of an absolute majority in the 300-seat parliament, making it unclear how a new government will be formed.

"It is up to Greek political forces to work in a spirit of responsibility to form a government with a stable majority," said Ahrenkilde Hansen.

She added that the commission stands ready to continue helping Greece implement the unpopular reforms attached to the bailout package, seen as contributing to electoral gains made by neo-Nazi and far-left parties.

Despite renewed fears that Greece could be forced to abandon the euro, the spokeswoman reiterated the commission's "confidence as far as the future of Greece inside the eurozone."
