Prime Minister Aleksandar Vucic, a former ultranationalist now a declared pro-European Union politician, is slated to win the presidency by a high margin against 10 opposition candidates, including a parody candidate who is mocking the country's political establishment. The prime minister since 2014, Vucic expected to use his win to appoint a figurehead successor and transform the presidency from a ceremonial office into a more muscular role — and rule unchallenged like Russian President Vladimir Putin, who has endorsed him. Vucic's main challengers in the vote include human-rights lawyer and former Ombudsman Sasa Jankovic, former Foreign Minister Vuk Jeremic and firebrand nationalist Vojislav Seselj, who has been tried for war crimes.
