(ANSA-AP) - ZAGREB, DECEMBER 20 - Croatia is holding a tight presidential election this weekend that is seen as a test for the conservative government only days before the European Union's newest member state takes over the bloc's presidency for the first time. President Kolinda Grabar Kitarovic is running for a second term at Sunday's vote facing a leftist former prime minister Zoran Milanovic, right-wing challenger Miroslav Skoro and eight others. The three front-runners are polling close to one another and analysts believe that the victor will be decided in a runoff on Jan. 5 since no single candidate is expected to win outright with a majority of votes. Keeping the presidency is important for the ruling conservative Croatian Democratic Union party as its government prepares to assume the EU chairmanship that will include presiding over Brexit and the start of post-Brexit negotiations.
