Litvinenko has moved to the United Kingdom in 2000. Six years later he was naturalized, however, the very same year, he began to feel ill. Litvinenko died in late November 2006, with UK doctors explaining his death by radiation poisoning.

According to a report by Robert Owen, the chairman of the UK inquiry into the death of Litvinenko, Russian authorities were responsible for taking his life in 2006. The report concluded that Litvinenko's former colleagues Dmitry Kovtun and Andrey Lugovoy deliberately poisoned him with polonium-210.

The investigation, however, failed to prove that the polonium-210, allegedly used to poison the former intelligence officer came from Russia.

The Russian Foreign Ministry refuted allegations about Litvinenko's murder and criticized the UK inquiry as politicized and lacking transparency, saying that it would have an adverse effect on relations between the two nations.
