Earlier, Lugovoy said that he had passed a polygraph test conducted by the British experts that had proved that he was not guilty.
"As we expected, there was no sensation. The results of the inquiry that were announced today once again confirm London's anti-Russian stance, narrow-mindedness and reluctance to establish the true cause of Litvinenko's death," Lugovoy told RIA Novosti.
On Thursday, the British Court blamed Russia for Litvinenko’s death but could not conclude that the polonium-210 had come from Russia.
According to the politician, the scandal around Litvinenko's killing became a "convenient way for London to achieve its political interests."
"This was clear to me from the very beginning," he added.
Following his death, UK authorities claimed that Litvinenko's former colleagues had poisoned him with the radioactive isotope polonium-210. A public inquiry into Litvinenko's death was formally established by the UK government in July 2014.
