"I learned of my wife being followed while I was prime minister, and on one occasion I raised the issue of justification of such measures," Racan told Hina.
He stressed that he did not want to speak about this topic in the context of the ongoing presidential campaign.
"It is well known that as prime minister I was not satisfied with security services, and that some people in security services were not satisfied with me," Racan said, adding that major progress in the reform of security services had been made during his term.
"That obviously was not enough and that is why it is necessary to continue efforts to restore order in the work of the services to prevent any abuse," Racan said.
He said that he was worried about the security services reverting to the 1990s practice.
Racan made the statement when asked to comment on articles in the latest issue of the Globus weekly stating that in 2002 the POA, headed by Franjo Turek, had investigated Racan's wife Dijana Plestina.
Slobodna Dalmacija daily today quoted Turek as saying that Racan was familiar with the investigation and that Plestina herself had approved it on two occasions, the first time when she filled in a security questionnaire before she was employed with the Foreign Ministry and the second time at the request of NATO, when she was to attend a NATO meeting.
