WARSAW: Poles voted on Sunday in parliamentary elections that will determine the country's future ties with the European Union and neighbouring Ukraine, as the ruling populists bid for a third consecutive term in power.
Opinion polls indicate the nationalist Law and Justice (PiS) party will get the most votes but may struggle to build a governing coalition, giving a chance to the opposition led by former EU chief Donald Tusk.
Polling stations across the EU and NATO member opened at 0500 GMT and will close at 1900 GMT, with exit polls expected immediately after and final results on Monday. Some 29 million people are eligible to vote, including half a million registered abroad in a large diaspora.
A PiS victory could exacerbate tensions with the EU and Ukraine and will dismay campaigners concerned about the future of media freedoms, women's and migrants' rights.
"It's time for a change," said Ewa Bankowska, a 43-year-old working in finance, told AFP as she voted in Halinow, a town just outside the capital Warsaw.
"I'm concerned about the economy. I would like us to develop and for the government to stop spending money it does not have," she said.
But Dorota Zbig, a 57-year-old nurse, said the last few years of PiS government "have been very good for me and my family and I hope everyone including young people votes reasonably."
At PiS's last major rally on Friday, party leader Jaroslaw Kaczynski said he wanted Poland to stay in the EU but that it should be a bloc of "sovereign countries."
Tusk told supporters from his Civic Coalition party the government was "leading the country down the wrong path."
"This is the most important day in the history of our democracy since 1989," Tusk said.
Opposition hopes for upset
PiS has vowed to press ahead with controversial reforms of the judiciary which it says are aimed at rooting out corruption but which the EU sees as undermining democracy.
The row has blocked billions of euros in EU funding.
The most likely coalition partner for PiS would be Confederation, a far-right party that has called for an end to Poland's large-scale assistance for Ukraine and has campaigned on a strongly anti-migrant platform. But Confederation has publicly ruled out such an alliance and some analysts say it is unlikely to happen because of simmering tensions between the two parties.
The hope among liberals is that, even if Tusk's Civic Coalition comes second, it will have enough votes to form a government with two smaller potential allies.
The elections are for the lower and upper houses of parliament and PiS has organised a referendum on the same day with leading questions on migrants and the economy, which the opposition has called for people to boycott.
Supporters of PiS say victory on Sunday will allow the party to fulfil its vision of a strong, sovereign Poland based on traditional Catholic values.
The campaign has been characterised by personal attacks on Tusk by the ruling party, which has accused him of working in the interests of Germany, Russia and the EU.
PiS has also ramped up anti-migrant rhetoric, with Prime Minister Mateusz Morawiecki saying the country should be protected against illegal immigrants "who have no respect for our culture".
'Damage will have been done'
Ukraine and its Western supporters are also watching warily in case Poland follows Slovakia, which last month elected a government that promises to take a much more sceptical view on sending aid to Ukraine.
Poland has been a leading cheerleader for Ukraine in the EU and NATO and has taken in a million Ukrainian refugees, but there is growing fatigue among many Poles. The government has also fallen out with Ukraine over a grain import ban aimed at protecting Polish farmers.
Marcin Zaborowski, an expert at the Globsec think tank, said the ruling party has adopted a chillier stance towards Ukraine in a bid for nationalist votes. "After the elections, it may be too late to go back on this since the damage will have been done," he said.
