Controversy

During the 2000 Polish presidential election, a film was published revealing Siwiec, then the chief of the BBN, allegedly parodying a gesture of Pope John Paul II (making a cross sign in the air on arrival). In November 2007, the Institute of National Remembrance (IPN; a commission for the prosecution of crimes against the Polish nation), revealed that in 1986 he was registered as an unofficial collaborator until January 1990. Marek Siwiec denied those claims. After concluding its own investigation, on 26 March 2009 the IPN, decided to discontinue the proceedings due to a lack of evidence about collaboration.^[4]
