Who is Gleb Karakulov? Vladimir Putin’s protection officer defects

An officer with the Kremlin's bodyguard agency who defected last year over his opposition to the Ukraine invasion provided intimate details about Russian President Vladimir Putin to a London-based investigative group, describing him as "paranoid" and calling him a "war criminal." The defector, Gleb Karakulov, was a captain in the Federal Protection Service (FSO) at the time of his defection in October.
