LONDON (Sputnik) — Earlier in the day, the British inquiry blamed Litvinenko’s death on Russian authorities but could not conclude that the polonium-210 used to poison the former agent had come from Russia. The Russian Foreign Ministry said that the UK inquiry was politicized.
"What happened was absolutely appalling and this report confirms what we've always believed, and what the last Labour government believed at the time of this dreadful murder, which is it was state sponsored action," Cameron told ITV.
"This shocking even was reacted to years ago when it happened and we're toughening our action again today," the minister said.
Following his death, the 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.
Earlier, Lugovoy said that he had passed a polygraph test conducted by British experts, that proved he was not guilty of murdering Litvinenko.
