Four-part drama based on the true story of the police investigation into the poisoning of the former Russian spy, Alexander Litvinenko.
In November 2006, Litvinenko, a former KGB officer, 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.
The four-part drama will air on ITV1 on consecutive nights starting from Monday 19th June at 9pm, with a documentary special titled Litvinenko: The Mayfair Poisoning then following at the same time on Friday 23rd June.
The drama – which is written by Lupin's George Kay – follows the true story (https://www.radiotimes.com/tv/drama/litvinenko-itvx-true-story-exclusive/) of the Metropolitan Police's investigation into the fatal poisoning of the titular Russian
defector in 2006, as they strive to prove who was responsible for his death.
Tennant stars as the former Russian Federal Security Services officer while the cast (https://www.radiotimes.com/tv/drama/litvinenko-itvx-cast/) also includes Margarita Levieva as Marina, Mark Bonnar as DS Clive Timmons, Neil Maskell as DI Brent Hyatt and Sam Troughton as DI Brian Tarpey.
And although Tennant is playing the title role, director Jim Field Smith explained last year that the star was actually only on set for "around 10 days" of shooting (https://www.radiotimes.com/tv/drama/litvinenko-david-tennant-filming-newsupdate/), given his character dies towards the start of the drama.
Kay previously said of the series: "In late 2006, Alexander Litvinenko was a living witness to his own murder. He spent his dying days entrusting the Metropolitan Police with the details of what happened to him.
"It took those police and his remarkable widow Marina Litvinenko a decade to have those claims ra
tified. Their stamina, hard work and bravery are what make this not only an essential story of our times but a privilege to be asked to write."
