Alexander Valterovich Litvinenko was a British-naturalised Russian defector and former officer of the Russian Federal Security Service (FSB) who specialised in tackling organised crime. A prominent critic of Russian President Vladimir Putin, he advised British intelligence and coined the term "mafia state".

The Federal Security Service of the Russian Federation is the principal security agency of Russia and the main successor agency to the Soviet Union's KGB; its immediate predecessor was the Federal Counterintelligence Service (FSK) which was reorganized into the FSB in 1995. The three major structural successor components of the former KGB that remain administratively independent of the FSB are the Foreign Intelligence Service (SVR), the Federal Protective Service (FSO), and the Main Directorate of Special Programs of the President of the Russian Federation (GUSP).
