George Papandreou in the context of "Panhellenic Socialist Movement"

Following the 4 October 2009 general elections in Greece, George Papandreou, the leader of PASOK, formed a government, which was sworn in on 7 October. A major cabinet reshuffle was made in September 2010. The cabinet was succeeded by the Lucas Papademos's Coalition Cabinet.

Early parliamentary elections were held in Greece on 4 October 2009. Elections were not required until September 2011, but on 2 September 2009 Prime Minister Kostas Karamanlis of New Democracy announced that he would request President Karolos Papoulias dissolve Parliament and call elections. Parliament was dissolved on 9 September.

The result was a victory for the opposition PASOK party led by George Papandreou, who became the new prime minister. New Democracy lost 61 of its 152 seats, with its vote share dropping by over 8 percentage points.

The Cabinet of Lucas Papademos succeeded the cabinet of George Papandreou, as an interim three-party coalition cabinet, leading a coalition government formed by the Panhellenic Socialist Movement (PASOK) party, New Democracy party and Popular Orthodox Rally party, after Papandreou's decision to step down, and allow a provisional coalition government to form with the task to take Greece out of a major political crisis caused by the country's debt crisis. It was the first coalition cabinet in Greece since the 1989–1990 Ecumenical Cabinet of Xenophon Zolotas.

The Prime Minister Lucas Papademos and the Cabinet were formally sworn in on 11 November 2011.
