Committee for State Security
In 2018, Bulgaria's state Dossier Commission announced that Kristeva had been an agent for the Committee for State Security under the code name "Sabina". She was supposedly recruited in June 1971. Five years earlier she left Bulgaria to study in France. Under the People's Republic of Bulgaria, any Bulgarian who wanted to travel abroad had to apply for an exit visa and get an approval from the Ministry of Interior. The process was long and difficult because anyone who made it to the west could declare political asylum. Kristeva has called the allegations "grotesque and false". On 30 March, the state Dossier Commission began publishing online the entire set of documents reflecting Kristeva's activity as an informant of the former Committee for State Security. She vigorously denies the charges.
