Nikolai Platonovich Patrushev is a Russian politician, security officer and former 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 played a key role in the decisions to seize and then annex Crimea in 2014 and to invade Ukraine in 2022. He is considered as very hawkish towards the West and the United States. Patrushev is seen by some observers as one of the likeliest candidates for succeeding Putin.
