ATHENS, Greece (AP) — Greece is heading toward a new general election two days after Prime Minister Kyriakos Mitsotakis’ center-right New Democracy party won a landslide victory in a national vote but failed to clinch a majority in parliament. A power-sharing deal was put mathematically out of reach after the main opposition party formally received and summarily rejected an invitation to try and form the country’s next government. Mitsotakis had swiftly ruled out seeking a coalition, opting instead for a second election expected on June 25. That would introduce a change in the electoral system that favors the winning party and likely hand him an outright victory.
