Sanader made the statement after a meeting of the National Security Council (VNS) that was attended by President Stjepan Mesic, Parliament Speaker Vladimir Seks, Supreme Court President Branko Hrvatin, and representatives of institutions involved in the fight against corruption.
Asked to comment on the Opposition's request, Sanader said he would be glad if the Opposition did not always bring party interests to the fore, but rather commended the government and encouraged its efforts.
Asked if his ministers were politically responsible for corruption in the HFP, Sanader said he trusted the State Prosecutor's Office and institutions which carried out the operation.
"Those who were involved, in one way or another, have been arrested and are no longer free," the PM added.
President Stjepan Mesic said that the names of government ministers were not being mentioned in the ongoing investigation.
"No ministers are being mentioned in the process of identifying those who abused their positions. If they were mentioned, they would be where the three tenors are now," Mesic said, alluding to the three HFP vice-presidents arrested on suspicion of corruption.
Mesic, Seks and Sanader said the VNS today discussed the extent to which its conclusions on the fight against corruption, adopted last September, had been implemented.
All three said they had known that a clampdown on corruption was under way, but they did not have information on which operations were being carried out.
Today's session was held for the purpose of consultation because the VNS wanted to know about the stage of the anti-corruption campaign and its future course.
"We are not talking about one, but a number of operations. We were not told today which operations are under way, nor will we be told, because that is not our job, but it is our job to see that state institutions are functioning," Mesic said.
Sanader underlined that the state leadership was determined to fight corruption.
"What was going on was not only bribery and corruption, but organised crime," he said.
The PM announced that the government would today replace the HFP vice-presidents involved in the scandal and set up a task force to draw up a law that would replace the Law on the HFP.
Parliament Speaker Seks underlined the parliament's contribution, saying that it had amended a number of laws to create conditions for the efficient work of the police and the judiciary.
Supreme Court President Branko Hrvatin said that the judiciary would act independently in the fight against corruption and that judges would be impartial.
