Greek Prime Minister George Papandreou survived a confidence vote early Saturday, calming a vicious revolt in his Socialist party with an emotional pledge to step aside if necessary and seek a cross-party government lasting four months to safeguard a new European debt agreement.

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