Parliamentary elections were held in Finland on 20 and 21 March 1966.[1] The Social Democratic Party (SDP) overtook the Centre Party as the largest faction in Parliament. Rafael Paasio of the SDP subsequently became Prime Minister and formed a popular front government consisting of the SDP, the Centre Party, the People's Democratic League (SKDL), and the Social Democratic Union of Workers and Smallholders (TPSL) in May 1966.[2][3]
