Former prime minister and one-time leader of the Social Democratic Party (SDP) Zoran Milanovic on Monday confirmed that he would run for president of state.
Milanovic posted a photograph of himself on his Facebook profile with the logo "A president with character", without any additional comments.
Unofficial sources have said that Milanovic would make a public statement later in the day regarding his candidacy.
The SDP's presidency convened in the afternoon and unofficial sources have said that it will make a recommendation to the party's Main Committee that Milanovic runs as the SDP's candidate in the presidential election.
Milanovic led the SDP from 2007 to 2016 and from December 2011 to January 2016 he was the country's prime minister after an SDP-led coalition won at the parliamentary election.
After serving as party leader and prime minister, he dedicated himself to private business.
