WARSAW, Poland (AP) — The majority of voters in Poland's general election supported opposition parties that promised to reverse democratic backsliding and repair the nation's relationship with allies, including the European Union and Ukraine, according to projections Monday.

After a bitter and emotional campaign, turnout was projected at almost 73%, the highest level in the country's 34 years of democracy and surpassing the 63% who turned out in the historic 1989 vote that toppled communism.

The opposition parties faced many disadvantages in contesting the election, said Jacek Kucharczyk, president of the Institute of Public Affairs, a Warsaw think tank. The governing party mobilized its administrative resources to help itself, including by controlling the election administration and by an unfair division of votes in electoral districts, he said.

The Ipsos poll showed Law and Justice with 36.6% of the votes cast; the opposition Civic Coalition, led by former European Council President Donald Tusk, with 31%; the centrist Third Way coalition with 13.5%; the Left party with 8.6%; and the far-right Confederation with 6.4%.

The electoral commission said it expected to report the final result Tuesday.

Even if the opposition parties take power, they will face difficulties in putting forward their agenda. The president will have the power to veto new legislation, while the constitutional court, whose role is to ensure that new laws don't violate the basic law, is loyal to the current governing party, Kucharczyk said.

“Fixing the relations with the EU in particular will require domestic changes, namely restoring the independence of the judiciary, restoring the rule of law, which is a condition for the EU to release the funding for Poland,” Kucharczyk said. “It will be a very, very prolonged and difficult process."
