Plenković said that Milanović's proposal that members of the Croatian parliament should vote against the accession of Finland and Sweden to NATO was perfidious.
"He (Milanović) has not said that he will block their accession. He has disseminated a perfidious, even worse claim. It was him who said that he would call MPs traitors and he insisted that the Parliament should block (their accession)," Plenković said explaining "the perfidious situation" created by Milanović.
The PM elaborated that this political game was aimed at destabilising Croatia's institutions, the government, and doing harm to the Croats in Bosnia and Herzegovina.
He also noted that as far as he could see, only Milanović was against Sweden's and Finland's membership of the alliance, while nobody else in NATO supported such idea.
"Such attitude against NATO's expansion is a pro-Russian stance. He is the only one who advocates that. Only those who advocate pro-Russian views can be satisfied with such attitude," Plenković said, recalling Milanović's criticism of Ukraine.
Plenković noted that Milanović's pro-Russian position does harm to Croatia in international circles and also to the Croats in Bosnia and Herzegovina.
As for the election law in Bosnia and Herzegovina, Plenković said that the election system in that country was bad not only for the Croats but also for the whole of Bosnia and Herzegovina.
Croatia's government believes that the election law must be amended, he added.
The government works on that consistently, it holds talks with the Bosniaks, the Croats and partners in the international community on that topic, Plenković added.
