Greek president to meet political leaders Sunday in last-ditch coalition effort

ATHENS, Greece - Greek President Karolos Papoulias has called the leaders of Greece's political parties to meetings on Sunday, in a last-ditch effort to broker a deal for a coalition government.

Papoulias' office announced Saturday that the president would meet initially with the heads of the three parties that won the most votes in Sunday's inconclusive elections — the conservative New Democracy, radical left-wing Syriza and socialist PASOK. He will then meet individually with the leaders of the other four parties that won enough votes for parliamentary seats.

If Papoulias fails to broker a coalition agreement, Greece will have to hold new elections next month.
