Pupovac told reporters he had seen Loncar vote instead of Cehok, who at the time was not in the parliament hall, and that his party colleague Vojislav Stanimirovic could back his claim.
Although Ivas admitted having voted instead of Cehok, Loncar claims that Pupovac repeated in an interview with a daily that it was Loncar who he had seen vote.
Locar said that Ivas told him that Pupovac had contacted him and told him not to fall for Loncar's attempts to get him involved in the case.
"Pupovac was seen through long ago, he uses every opportunity to set ultimatums and to blackmail to the detriment of his own country, everybody in Croatia, regardless of their ethnic background and religion, are tired of his lies, his fake concern and patriotism and pathetic speeches," Loncar said.
Pupovac was unavailable for comment today.
Commenting on the incident in parliament, Liberal Party (LS) leader Zlatko Kramaric said in Osijek today this was "the culmination of travesty of our parliamentarism" and added that in normal democracies a deputy voting instead of another deputy would never be able to sit again in the parliament.
"That man (Ivas) even refers to Christian values, while the church, the public and the parliamentary presidency keep silent," Kramaric said.
