OSLO — Norwegians decided in a parliamentary election Monday to shift the power in the oil-rich nation for the first time since 2005 to a center-right coalition, including an anti-immigration party.
A projection by Statistics Norway, based on about 40 percent of the vote, indicates Conservative Party leader Erna Solberg will become the new prime minister, replacing Jens Stoltenberg of the Labor Party.
Stoltenberg conceded defeat late Monday and congratulated his opponent. He said his party tried ‘‘to do what almost no one has done, to win three elections in a row, but it turned out to be tough.’’
Despite Norway’s strong economy and low unemployment, the Conservative Party saw a surge in support amid pledges to increase the availability of private health care and cut taxes on assets over $140,000.
The conservatives have said, for the first time, that they are prepared to form a coalition government with the anti-immigration Progress Party, which appears to have lost support since 2009 but is still the third largest party in Norway. It may also seek the support of the Liberal Party and the Christian Democrats.
The vote projection showed the Conservative Party got 26.2 percent of the votes. Together with its potential coalition allies — the Progress Party, the Liberal Party and the Christian Democrats — it was forecast to get 52.8 percent of the votes.
The Labor Party was expected to remain the biggest single party, with 30.7 percent of the votes. Still, the party and its two coalition partners, the Socialist Party and the Center Party, had only 42 percent of the votes in the projection.
