Sanader also demanded that such a commission should also investigate the role of current Prime Minister and HDZ leader Jadranka Kosor in the case.
Sanader today held a news conference in the parliament following media speculations that a former customs administration's chief, Mladen Barisic, has accused him of having received money syphoned off from public companies at the time when he was Prime Minister.
Dismissing the media speculations, the former premier said that such reports were part of the "political programme of Jadranka Kosor", his successor in the post of Prime Minister.
Sanader said that Kosor had lost public support and that "she has practically shown that she is incapable of running the government."
Kosor "is incapable of dealing with the serious economic situation and of pulling the country out of the crisis, which is why she is orchestrating political persecution in order to shift public attention from the real problems that are troubling citizens," Sanader said at the news conference.
He said that Kosor was being assisted by Seks in enforcing "undemocratic and anti-constitutional methods".
The best example is the case of Damir Polancec, who was blackmailed and offered freedom in return for a false testimony against me, Sanader said, adding that Judge Ivan Turudic obviously was to have had a role in this.
The Zagreb County Court recently sentenced Polancec, a former Deputy Prime Minister and Economy Minister, to 15 months in prison pending appeal for paying Vukovar attorney Petar Miletic half a million kuna of budget funds for an unnecessary expert study. The panel of judges, presided over by Turudic, sentenced Miletic to one year in prison pending appeal, ordering that he and Polancec pay back the amount in question.
That the Croatian judiciary is politicised is confirmed by a message from the European Commission, conveyed by a part of Croatian media, about the need for Croatia to depoliticise the judicial system to close the policy area No. 23 (Judiciary and Fundamental Rights), Sanader said.
Although he deems Kosor to be incapable, Sanader still does not want to topple the current parliamentary majority.
He said that under his helm the HDZ had won the 2007 election victory, which paved the way for the present majority in the parliament.
"This is my mandate and the mandate of people who together with me won the election. The mandate was obtained thanks to a certain political platform verified by voters and it must be carried out," Sanader said, adding that the mandate was not given by voters for "political settling of scores with political opponents".
In response to reporters' question whether he made a mistake when he nominated Jadranka Kosor to be his successor as Prime Minister, Sanader answered, "She was my choice. I proposed her nomination to the party and to the parliament and to the coalition partners. Everybody accepted it. Anyone can be wrong, so can I," he said.
He declined to say who from the HDZ could take over the government.
As regards Seks, whom he accused of having a clout on the judiciary, Sanader said that while he was Prime Minister he had reduced Seks's influence by not proposing that he be reappointed parliament speaker.
