A "kotiryssä" (literally "Home Russian") is a Soviet or Russian contact person of a politician, bureaucrat, businessman or other important person in Finland. The dozens of KGB officers working out of the Tehtaankatu embassy of the Soviet Union is now well documented. The public did not know about the system until the book Tamminiemen pesänjakajat was published in 1981. The kotiryssä system was closely related to Finlandization.
