In Romania's 2004 legislative election, held on 28 November, no party won an outright majority. The Social Democratic Party (PSD) won the largest number of seats but is currently in opposition because the Justice and Truth Alliance, the Democratic Union of Hungarians in Romania, the Romanian Humanist Party (which later became the Conservative Party), and the National Minorities formed a governing coalition, giving it 177 seats in the Chamber of Deputies (47.9% of the total). The Conservative Party withdrew in December 2006, meaning that the government lost the majority in the Chamber of Deputies. In April 2007 the liberal prime-minister, Călin Popescu-Tăriceanu, dismissed the Democratic Party ministers from the government and formed a minority government with the Democratic Union of Hungarians in Romania, marking the end of the Justice and Truth Alliance.
