Nikolai Platonovich Patrushev (Russian: Никола́й Плато́нович Па́трушев; born 11 July 1951) is a Russian politician, security officer and intelligence officer who has served as the secretary of the Security Council of Russia since 2008. He previously served as the director of the Federal Security Service (FSB) from 1999 to 2008. Belonging to the siloviki faction of president Vladimir Putin's inner circle, Patrushev is believed to be one of the closest advisors to Putin and a leading figure behind Russia's national security affairs. He is considered as very hawkish towards the West and the US and has promoted various conspiracy theories. Patrushev is seen by some observers as one of the likeliest candidates for succeeding Putin.
