Panhellenic Socialist Movement in the context of "George Papandreou"

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.

From the restoration of democracy in 1974 to the 2012 elections, the characteristic Greek political system was predominantly a two-party system. The historically dominant parties were New Democracy and the Panhellenic Socialist Movement (PASOK). Under the electoral system, a party needs to surpass a 3% threshold in the popular vote in order to enter parliament. Until 2023, the largest party used to get a 50-seat bonus (out of 300 seats), ostensibly to ensure elections returned viable governing majorities. The 2023 Greek legislative election was the first and only that was held without the 50-seat bonus rule. Although New Democracy achieved a large percentage of 40.7% and beat the opposition party by 20%, they fell short of forming a majority by 5 seats. The Hellenic Republic had a caretaker prime minister until the June 2023 Greek parliamentary election was held.

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.
