"It's not my intention to spread paranoia, but this has already happened to (Social Democratic Party deputy) Milanka Opacic and (Democratic Centre leader) Vesna Skare Ozbolt, and now it's happened to me," Adlesic said at a press conference in the Parliament building, adding that she had reported the case to Interior Minister Ivica Kirin.
Adlesic would not speculate on who was inquiring about her, but cited a possibility that it might be present or former intelligence agents or a private person wanting to discredit her in the election campaign.
Adlesic said she had not approached the Council for the Civilian Supervision of the Security Services because she thought "they can do nothing about it", but insisted that all such cases should be thoroughly investigated.
"I regret that in 2007 we have to discuss whether or not secret services are involved in an election campaign," she said.
Commenting on her allegations, the chairman of the Parliament Home Affairs and National Security Committee, Ivan Jarnjak, said that Adlesic should have reported the case to the Council for the Civilian Supervision of the Security Services and to his committee.
"We have a stable system. The services are absolutely under the supervision of this committee and the state leadership," Jarnjak said, adding that such unsubstantiated statements, especially when made during an election campaign, might affect the stability of the intelligence system.
Jarnjak said that his committee and the Council for the Civilian Supervision of the Security Services would look into all the cases reported to them.
Reporters also asked President Stjepan Mesic if the security services in Croatia were using their position to monitor political opponents, to which he said that he had read about it in the newspapers, but that he had received no official report.
"I will request that each such case be thoroughly investigated and if we find that someone crossed the line, that person will be punished. The intelligence services or the police should not be involved in politics. They should perform their duties as prescribed by law and should do nothing else," the president said.
