Tomislav Karamarko told a press conference on Tuesday that he was resigning as president of the Croatian Democratic Union (HDZ).
"I resign as HDZ president. Reasons are clear and multi-layered (...) I promised the party that I would manage to form a parliamentary majority and I have failed," Karamarko said ahead of the session of the HDZ presidency.
Karamarko's resignation followed after he resigned as Deputy Prime Minister last week and, as he said, after he failed to reshuffle a ruling majority following the toppling of the Tihomir Oreskovic government, initiated by the HDZ.
HDZ Secretary General Domagoj Ivan Milosevic said on Monday evening that most of the HDZ members expect party chief Karamarko to resign.
"I don't know what Tomislav Karamarko will do tomorrow, but what I can say clearly is that I am not one of those publicly calling for resignations, but over the past several days many party members from all parts of Croatia have called me, members of the party presidency, the head committee and the absolutely dominant position is that we expect Mr Karamarko to resign," Milosevic told Nova TV.
A member of the European Parliament, Adrej Plenkovic of the HDZ, told Croatian Television on Monday evening that he was prepared to run for HDZ president.
"In new circumstances, now that parliament has been dissolved and now that it has become clear that due to a wrong assessment a government reshuffle had failed following a vote of no-confidence in the government formed by the HDZ, its coalition partners and Bridge as the key partner, I believe we need to approach the new election fresh and in the context of this situation, I am prepared to take responsibility," Plenkovic said.
