In 1973, he and co-reporter Peter Bratt exposed a secret intelligence organization in Sweden, Informationsbyrån (IB). He is still active within journalism as a column writer for the Swedish evening tabloid Aftonbladet.In October 2009, it was revealed that Guillou had been recruited by the KGB in 1967. The exposure of his activities came after the tabloid Expressen requested the release of documents from the Swedish Security Service (Säpo) and published information from the Säpo files along with information gained through interviews with former KGB Colonel Oleg Gordievsky about Guillou's case. The records showed that Guillou's involvement with the KGB continued for five years, until 1972. From Wikipedia
