( AP ) - A pro-business opposition party that wants Poland's troops out of Iraq ousted Prime Minister Jaroslaw Kaczynski's government in parliamentary elections Sunday, as Poles opted for leadership offering a more cooperative approach to the European Union.
Donald Tusk's Civic Platform party led with 41.2 percent of the vote after nearly three-fourths of the ballots were counted early Monday, which would give the party 205 seats in the 460-seat Sejm lower house.
That would be short of the 231 needed for a majority - but close enough for it to join with a smaller party to form a government.
"Today I am the happiest person in the world," a teary-eyed Tusk told supporters. "People in Poland voted today to chose their own fate and have put a great responsibility, a great task on our shoulders. We undertake this great responsibility."
Kaczynski conceded defeat late Sunday, saying, "we didn't manage in the face of this unprecedented broad front of attacks," referring to the opposition's campaign.
His Law and Justice party got 32.2 percent of the vote, or 166 seats, according to partial results. Complete results are expected either later Monday or Tuesday.
Kaczynski said a coalition with the election winner was "out of the question" and pledged to use his time in the opposition to rebuild his forces - and keep a close check on the new government.
A hard-fought campaign generated voter turnout of 52.6 percent, higher than any parliamentary elections since the fall of communism in 1989, according to an exit survey conducted by the PBS DGA polling institute. The high turnout caused some polling stations to run out of ballots and stay open longer than scheduled, delaying the release of the first exit polls for hours.
The election result means Poland will no longer have twin brothers holding the two highest offices; Jaroslaw Kaczynski's brother, Lech Kaczynski, will remain the country's president with a term lasting until 2010. The 58-year-olds are former child movie stars who as adults became activists with the Solidarity trade union movement that helped topple communism in 1989.
Both Tusk and Kaczynski favor good relations with the United States, but Tusk argues Poland has not gotten enough from its close ties with Washington and wants the country's 900-strong detachment in Iraq to come home. He also says Poland should drive a tough bargain in return for hosting a missile defense base.
It is a stinging defeat for Kaczynski, whose socially conservative party was elected two years ago and has since been criticized for its assertive approach to the EU and efforts to purge former communists from positions of influence.
The 50-year-old Tusk, the favorite to become the next prime minister, said the election showed that Poles want to focus on the economic opportunities presented by the country's membership in the EU, which Poland joined in 2004.
"It is Civic Platform's intention to make Poles feel much better in their own country than they have felt so far," Tusk told supporters. "You have the right to rejoice today."
Kaczynski had sought the elections two years ahead of schedule after his party could not overcome bickering with the two smaller parties it needed to form a majority.
He has clashed with other EU countries over a new treaty to govern how the union makes decisions, demanding more say for Poland. He is also at odds with the EU over environmental protection, government backing for Polish firms, and the death penalty, which Poland does not have but Kaczynski supports.
The country's deployment of 900 soldiers to Iraq has been extended through the end of the year by the current government, but Kaczynski has suggested it could be extended again. Tusk's party, on the other hand, wants the troops to come home, although some party officials have said that could take as long as until the end of 2008.
Tusk's party also calls for additional security guarantees for Poland such as the U.S. Patriot short-range anti-missile and anti-aircraft system, and suggests Kaczynski has failed to win rewards such as visa-free travel for Poles to the United States.
Both Kaczynski and Tusk began their political careers as anti-communist dissidents in the Solidarity movement. Today, however, they part ways on how to deal with the ex-communists who were once their enemies.
Kaczynski favors a belated purge of ex-communists and their secret collaborators from public life - a reckoning purposely avoided in the peaceful transition of power. He maintains that the ex-communists continue to wield undue influence. But a court overturned his legislation to have up to 700,000 people, including journalists and teachers, screened for collaboration.
Tusk's party opposes that kind of reckoning, saying that Poland should not divert its attention from the new economic opportunities presented since the country joined the EU in 2004.
