(ANSA-AFP) - WARSAW, MAY 17 - The future of Poland's pro-EU government is riding on the country's presidential elections, which come at a fraught moment for Europe, analysts said ahead of the first round of voting on Sunday. The electoral campaign in the European Union and NATO member largely revolved around foreign policy, showcasing a clash of philosophies over Poland's engagement with the EU and the United States. "It was a kind of identity campaign," said Marcin Zaborowski, a fellow at think tank Globsec. "There was Ukraine, the attitude towards the European Union, towards migration, towards the United States," he told AFP. The job of Polish president is sometimes dismissed as a ceremonial post, but it comes with some real power. And that has often stymied Prime Minister Donald Tusk, a former European Council chief whose centrist Civic Coalition (KO) has clashed on multiple fronts with conservative President Andrzej Duda since coming to power in 2023. Tusk's KO is supporting pro-EU Warsaw mayor Rafal Trzaskowski for president. Duda, who cannot run again, is allied with Trzaskowski's top rival for the Belweder presidential palace, nationalist historian Karol Nawrocki, endorsed by the main opposition Law and Justice party (PiS). Thirteen candidates of all stripes are vying to be the next president of the Central European country of 38 million people. Trzaskowski is the frontrunner, with 33 percent of the vote in the latest opinion polls, compared with 26 percent for Nawrocki. With neither on track to win more than 50 percent, they will likely meet again in a runoff on June 1. The role of kingmaker could go to Slawomir Mentzen, the far-right Confederation party candidate, who is polling in third with 11 percent. (ANSA-AFP).
