Greece\'s Prime Minister George Papandreou has won a confidence vote in parliament. Papandreou has called for a coalition government, aiming to win parliamentary approval for Greece’s latest bailout. The open revolt against him erupted after Monday\'s announcement of a controversial referendum on the latest EU aid package to Greece. Calls for his resignation have grown from opposition parties, cabinet members and even from Papandreou’s own ruling socialist party. Lawmakers are calling for the creation of a national unity government and snap elections. A week of unending drama in Athens has spooked global markets and overshadowed the Group of 20 summit in the French resort of Cannes.
