After casting his ballot in Croatia's legislative elections, incumbent Prime Minister Andrej Plenkovic urges the country's citizens to vote for "responsible people" who will keep anchored within "the framework of NATO and the European Union", in a thinly veiled swipe at his populist challenger President Zoran Milanovic, who has criticised EU support for Ukraine. For months, Plenkovic seemed poised for an easy victory that would secure his third term as premier, but Milanovic's shock announcement that he would challenge Plenkovic has turned the polls into a showdown between the two arch-rivals.
