WARSAW, Sept. 25 (Xinhuanet) -- Poland's opposition center-right won the parliamentary election on Sunday with a broad lead over the ruling left-wing alliance, two exit polls showed.

    The conservative Law and Justice Party (PiS) won with 27.6 percent of votes and its ally Civic Platform (PO) with 24.1 percent, while the governing Democratic Left Alliance (SLD) got only 11.3 percent, according to an exit poll for the Polish public television.

    The other exit poll for the private television TVN gave PiS 28.3 percent and PO 26.4 percent, while the corruption-marred SLD lagged behind with 11.1 percent.

    According to the polls, the center-right opposition is expected to win at least 303 seats in the 460-member lower house of parliament, leaving 50 seats to the SLD.

    "We have won. Everything indicates that we have won, but this is only the beginning," said PiS leader Jaroslaw Kaczynski, who will be likely to become Poland's next prime minister.

    "We must rebuild many things in Poland," he said. "We must restore trust in the state, something which has been highly compromised in recent years."

    But the 56-year-old PiS leader said that he would not take the premiership if his twin brother Lech, Warsaw's mayor, wins the presidential race next month.

    PO leader Donald Tusk, who took lead in the opinion polls before the vote, conceded that PiS had done better than his party.

    "Now the time has come for us to see what we can do together for Poland, Tusk said.

    The PiS and PO agreed before the election that they would form a government together if they win.

    The fourth place went to the Union Self-Defense which garnered 10.2 percent of votes, and the League of Polish Familites got 8.2 percent, according to the TVN poll.

    The Peasants' Party was the only other grouping to reap more than 5 percent.

    The turnout of 40.3 percent in the ballot was the lowest for an election for more than 10 years, reflecting the Poles' dismay withthe current political situation.

    The two winning conservative parties, promising tax cuts and clean government, were divided over how far to go in embracing the free market and how much welfare the government can afford with wealth levels at half the European Union average.

    The PO has proposed a 15-percent tax rate and urged to move faster with privatization. The PiS favors state aid and government intervention in the economy.

    Their pre-election bickering has raised suspicion about what kind of economic policy their coalition government will adopt. Enditem
