Indeed - it is looking very likely that Greece will need to hold a new election.
From the BBC News website:-
Greece's centre-right leader, Antonis Samaras, has said he cannot form a coalition government, hours after he was given a mandate by the president.
His New Democracy, which backed the last EU bailout, emerged as the biggest party after Sunday's election, but he said a coalition was "impossible".
The Greek result, and France electing an anti-austerity president, have caused concern among EU leaders.
German Chancellor Angela Merkel warned that austerity measures must continue.
Mr Samaras said his party had done "everything we could" to form a government.
But he said it was impossible, so handed back the mandate.
President Karolos Papoulias has now arranged a meeting for Tuesday morning with Alexis Tsipras, who leads the anti-bailout Syriza leftist coalition, which came second in Sunday's vote.
Mr Tsipras will be given the right to start coalition talks, but analysts say he is likely to struggle to reach the numbers needed for a cross-party majority.
The BBC's Mark Lowen in Athens says Greece's political crisis is deepening, and the likelihood of fresh elections is growing ever stronger.
Despite emerging as the biggest party, New Democracy's support slipped from 33.5% in the last election to less than 19% on Sunday.
Support for the centre-left Pasok, which also supported the austerity measures, plummeted from 43% to just over 13%.
The major winners were anti-bailout groups - Syriza, with 16.8%, and the ultra-nationalist Golden Dawn, with almost 7%.
