ATHENS, Greece (AP) -- Greece's prime minister survived a confidence vote early Saturday, calming a revolt in his Socialist party with an emotional pledge to step aside if need be and seek a cross-party government lasting four months to safeguard Europe's new debt agreement.

George Papandreou won the critical confidence motion with a vote of 153-145 after a week of drama in Athens that horrified its European partners, spooked global markets and overshadowed the Group of 20 summit in the French resort of Cannes.
