Litvinenko Inquiry: Watch Closing Statements

The public inquiry into the murder of former Russian spy Alexander Litvinenko has helped "shine a light" on the lengths the Kremlin will go to silence dissent, according to his widow. As closing statements are made at the end of the six-month-long, London-based hearing, Marina Litvinenko told Sky News she does not believe the two Russian men accused of killing her husband will be brought to justice anytime soon, but said the inquiry has helped ensure the truth is more widely known. Alexander Litvinenko died in London's University College Hospital in November 2006 - three weeks after being poisoned by the deadly radioactive isotope polonium-210.
