Greek Prime Minister George Papandreou is seen in his car as he leaves the presidential palace in Athens November 9, 2011. Papandreou said he was stepping down on Wednesday without saying who would succeed him as the nation heads toward an economic precipice, but party sources said political leaders had agreed it would be the speaker of parliament. Parties from left and right settled on veteran socialist Filippos Petsalnikos, barring-last minute snags, the sources said, turning to their own political class after ditching a plan to recruit a former top European Central Bank official.
