Voters in Poland head to the polls for the second round of a tight presidential election, with major stakes for the country's role in the EU and its stance on abortion and LGBTQ+ rights. Rafal Trzaskowski, 53, the pro-EU mayor of Warsaw and ally of the centrist government, is up against Karol Nawrocki, 42, a nationalist historian backed by the conservative Law and Justice Party (PiS) of outgoing President Andrzej Duda.
