IB affair

The key persons leading to the exposure of the IB were journalists Jan Guillou and Peter Bratt and their original main source Håkan Isacson.

[3] Their revelations were that: In the following issues of Folket i Bild/Kulturfront the two uncovered further activities of IB and interviewed a man who had infiltrated the Swedish movement supporting the FNL, Vietnamese National Front for the Liberation of South Vietnam - at this time the FNL support network was a backbone of the radical opinion - and among other things, visited Palestinian guerilla camps in Jordan.

In 2009, he released an autobiography of his years in IB, attacking Guillou in particular for having misrepresented facts, been involved with Palestinian militant groups (particularly the Popular Front for the Liberation of Palestine and Democratic Front for the Liberation of Palestine), and worked for the KGB; and alleging widespread terrorist ties to the groups and persons monitored by IB.

Evidence was put forth in 1974 that IB had built up a large network of agents in Finland, which included the Finnish foreign minister Väinö Leskinen.

Jan Guillou, Peter Bratt, Håkan Isacson and the photographer Ove Holmqvist were arrested 22 October 1973[2] by the Swedish Security Service on suspicion of espionage.

Concerning the break-ins to the leftists' organization, the Ombudsman stated that since the personnel of IB had entered the premises using a key or a lock-pick and had not stolen anything it could not be considered a crime.

In 2002 an extensive public report, named Rikets säkerhet och den personliga integriteten (Security of the Realm and personal integrity), was published on the operations of IB.
