Zagreb, March 15. Croatian President Milanovic announced on social media on the 15th that he will participate in the Croatian parliamentary elections to be held on April 17 as an independent candidate from the Croatian Social Democratic Party and will run for the position of Prime Minister.

Milanovic said he was full of confidence in winning the election and would resign as president after winning the election and assume the responsibility of leading the Croatian government. Until then, he will continue to perform his duties as President of Croatia in accordance with the Constitution.

Milanovic’s announcement shocked Croatia, because there is no precedent for a president to run for prime minister in Croatian history. As a Social Democrat, Milanovic’s move will undoubtedly inspire the Social Democratic Party, which is currently at a disadvantage in the parliamentary elections, but it will also cause huge controversy. Croatian constitutional expert Baric told the media that the Croatian Constitutional Court should clearly tell Milanovic that he can only run for prime minister if he resigns as president.

According to the latest opinion poll, the ruling party, the Croatian Democratic Community, led by Croatian Prime Minister Prenkovic, ranks first with a support rate of 265%, and the Social Democratic Party ranks second with a support rate of 179%.

Milanovic was elected President of Croatia in January 2020. Previously, he served as Prime Minister of Croatia from December 2011 to January 2016. (Reporter Li Xuejun)
