Oreskovic's call was promptly rejected by the leader of the Croatian Democratic Union, Tomislav Karamarko, who said he was surprised by the prime minister's decision. Most leader Bozo Petrov said he was ready to resign but insisted Karamarko should too. After Prime Minister called on deputy prime ministers Tomislav Karamarko and Božo Petrov to resign,Zoran Milanović (SDP) said that the new elections will be held in September.
The Croatian parliament is due to hold a no-confidence vote over Karamarko's alleged conflict of interest by June 18.
Croatia's fragile coalition government has been rocked since the weekly newspaper Nacional reported in May that Karamarko’s wife, Ana Saric Karamarko, had received over 60,000 euros for alleged counselling service from a lobbyist for Hungarian energy company MOL, a company in dispute with Croatia.
