Poland votes today in elections which, if poll predictions are borne out, would see the country move to the right after four years of rule by the Democratic Party of the Left.
Surveys indicate the Law and Justice and Civic Platform parties will win around 60 percent of the vote.
The two parties are natural allies but are competing to be the dominant force in a ruling coalition.
The last polls suggested the pro-reform Law and Justice party, jointly led by Jaroslav Kacnynski, would have the upper hand.
Civic Platform, led by Jan Rokita, is pushing for more sweeping changes including a 15 percent flat tax rate.
The ruling leftist party appears to be paying the price for failing to reduce high unemployment, and for corruption scandals that have tainted the government.
The parliamentary elections will be followed in two weeks time by a presidential vote. The current president, Alexsander Kwasniefski is ineligible to seek a third term in office.
