The leader of Greece's left-wing Syriza bloc has said he will try to form a coalition based on tearing up the terms of the EU/IMF bailout deal.
Alexis Tsipras, whose bloc came second in Sunday's vote, said Greek voters had "clearly nullified the loan agreement".
He has three days to reach a coalition deal and has told the two major parties to end their support for the austerity terms if they want to take part.
French and Italian voters also rejected austerity candidates in Sunday polls.
On Monday, centre-right New Democracy leader Antonis Samaras abandoned attempts to form a coalition.
France's socialist President-elect, Francois Hollande, said in his victory speech that he would seek an alternative to austerity.
And results from local elections in Italy indicate a marked swing away from mainstream parties. An anti-euro protest movement led by comedian Beppe Grillo made significant inroads in Parma and Genoa.
In Greece, both New Democracy and former coalition partners Pasok, the traditional parties of power, saw their support drain away in favour of radical parties on the left and right.
