Russian investigators say Sergei Skripal, 55, received about $100,000 from MI6 over a period of several years for the information, which included the identity of dozens of Russian undercover intelligence agents working in Europe.
Russia's chief military prosecutor, Sergei Fridinsky, voiced satisfaction at Skripal's sentence, calling it "lawful and justified."
The Russian daily "Izvestia" reports that Skripal's activities seriously disrupted Russia's espionage activities in Europe.
