2010 Czechoslovak federal election (WFAC)

Federal elections were held in Czechoslovakia on 28 and 29 May 2010. All 300 seats in the Federal Assembly were up for election, with MPs elected by party-list proportional representation.

The election saw a increase of support for the Social Democrats (ČSD), and they received the highest number of votes. Despite a slight loss of support for the conservative Republican Party (RS), they, along with the christian democratic Czechoslovak People's Party (ČSL) and its sister party, the Slovak People's Party (SĽS), and the liberal Free Democrats (SD–LS) won the election, and the four parties announced their intention to form a new centre-right government with the incumbent Miroslav Kalousek as Prime Minister. Their main opponent, Robert Fico's Social Democrats (SPD), conceded defeat.
