The leaders of Greece's once-dominant political parties are making their final effort to form a coalition and avert an imminent new election.
A poll shows an election would all but wipe them out and give victory to a radical leftist who rejects an EU bailout.
The overwhelming majority of Greeks want to stay in the euro zone but voted last Sunday for parties that reject the severe terms of a bailout negotiated last year.
European leaders say Greece will be ejected from the common currency if it turns its back on the package of tax hikes and wage cuts.
Socialist Pasok leader Evangelos Venizelos, whose party was once strong but placed a distant third in the election, is the last politician given a chance to form a government.
He will meet with conservative rival Antonis Samaras, whose New Democracy party came first in the election, but who has already failed to form a coalition.
