In May 1973, the Swedish journalists Peter Bratt and Jan Guillou exposed the secret Swedish intelligence service IB in the magazine Folket i Bild/Kulturfront. The secret Swedish intelligence service had among other things, engaged in opinion registration, burglary at various Stockholm embassies and agent infiltration of the Palestinian groups and the FNL movement. Peter Bratt and Jan Guillou were later arrested and sentenced to prison for espionage for their reporting on IB, which turned the IB-affair into a political scandal, as apposed to just a political affair.
In 2017, sociologist Alexandra Franzén conducted interviews with Peter Bratt and Jan Guillou regarding how they experienced the the IB-publication, and their views on various issues concerning the limit of freedom of expression in democracies when it comes to Swedish journalism and the mass media and the scrutiny of intelligence services.
This article compares the interview results from 2017 with the statements Peter Bratt and Jan Guillou made in the original police interrogations in 1973.
