In the March 2004 elections, PASOK was defeated by New Democracy, led by Kostas Karamanlis, the nephew of the former president. The government called early elections in September 2007 (normally, elections would have been held in March 2008), and New Democracy again was the majority party in the Parliament. As a result of that defeat, PASOK undertook a party election for a new leader. In that contest, George Papandreou was reelected as the head of the socialist party in Greece. In the 2009 elections however, PASOK became the majority party in the Parliament and George Papandreou became Prime Minister of Greece. After PASOK lost its majority in the Parliament, ND and PASOK joined the smaller Popular Orthodox Rally in a grand coalition, pledging their parliamentary support for a government of national unity headed by former European Central Bank vice-president Lucas Papademos.
