The six-party coalition government of Finnish Prime Minister Jyrki Katainen has been sworn in two months after national elections.

Earlier Wednesday, the parliament overwhelmingly elected the conservative party leader as the new prime minister. Mr. Katainen was finance minister in the outgoing center-right coalition government.

Mr. Katainen, whose party won the April elections, has formed what he calls a “rainbow” government with the Swedish People's Party, the Christian Democrats, the Social Democratic Party, the Greens and the Left Alliance.

The coalition will form a majority with 126 of the 200 seats in Finland's parliament. The True Finns, which made big gains in the election to become parliament's third largest party, declined to join the coalition, citing their opposition to bailout packages for debt-ridden European countries.
