The elections were a major victory for the opposition National Coalition Party under Jyrki Katainen. It gained ten seats and became the second-largest party in Finland. The main government partners, the Centre Party and the Social Democrats, both lost ground. With the Left Alliance also losing seats, the labour parties received the worst result in the 100-year history of Finnish democracy; for the Social Democrats, the result was the worst since 1962, while the Left Alliance has lost seats in both elections held since 1999. The Centre Party, despite the loss, maintained its position as the biggest party in Parliament, with one seat more than the National Coalition. It was also the only time, except for the parliamentary election of 1930, that the Centre Party and the National Coalition Party together have an absolute majority in Parliament. The outcome led to the formation of a new center-right government and the left-leaning Social Democrats were left out in opposition for the first time since 1995.
