General elections were held in Sweden on 16 September 1979. Although the Swedish Social Democratic Party remained the largest party, winning 154 of the 349 seats in the Riksdag, the liberal interim government of Ola Ullsten was succeeded by another centre-right coalition government composed of the People's Party, the Moderate Party and the Centre Party, led by Centre Party leader Thorbjörn Fälldin. The three parties won 175 seats to the 174 held by the Social Democrats and Communists. Until 2010, this remained the only successful re-election of any non-socialist government in Sweden since the 1920s. The Moderates dramatically increased their seats, becoming the largest party of the non-socialist bloc, a position the party retains until today.
