President Kolinda Grabar-Kitarovic has requested the National Security Council to launch an investigation into the leak of a document from the Security and Intelligence Agency (SOA)
The HDZ said it expected the media to check facts thoroughly and not rush with conclusions based on imputations, wondering why and how such a document could have been published.
Raskovic was elected a member of Parliament on the Independent Democratic Serb Party (SDSS) slate, but has in the meantime left the party.
"Should the indications of attempts to snatch seats prove to be true, we will have to seek protection of state institutions, because such things cannot be tolerated," Pupovac said.
Asked if it was true that Raskovic had left the SDSS, Pupovac replied with a brief text message: "He did, today at 08:01 hours, by a letter to the SDSS president and presidency."
Raskovic should say whom he met in one of Zagreb's hotels a day before Wednesday's consultations when he was supposed to be in the SDSS, and what the talks were about.
He said earlier that he would abide by the party's position and then disregarded the SDSS Presidency's decision to support the left-wing coalition.
