ITV’s four-part drama series Litvinenko airs on Thursday (December 15), based on the true story of the police investigation into the poisoning of Alexander Litvinenko (played by David Tennant ). In November 2006, Litvinenko – a former Russian agent – lies dying in a London hospital, poisoned by a mysterious radioactive substance.
As police are summoned to take his statement, Litvinenko points his finger directly at the Russian President, Vladimir Putin. Litvinenko’s death a few days later sparks an investigation into a chemical attack on the streets of London and a ten-year investigation between Britain and Russia to find justice for his murder.
As well as a dramatisation of one of the infamous assassinations in modern times, Litvinenko also follows the former Russian agent’s wife Marina and her long fight to bring those responsible to justice.
