Polish nationalist opposition candidate Karol Nawrocki won the second round of the country's presidential election with 50.89% of the votes, the electoral commission said early on Monday, in a blow to the reform agenda of the pro-European government.
His rival, Rafal Trzaskowski, the liberal Warsaw mayor and an ally of the government led by Donald Tusk, got 49.11%. An exit poll on Sunday had shown Mr Trzaskowski winning with a razor-thin majority.
