ITV has shared a first look at David Tennant as Alexander Litvinenko, recreating the famous photo of the Russian defector lying in hospital before his death from poisoning.
A new TV drama – due to launch on ITVX next month – will explore the story of the Metropolitan Police officers who investigated the case of Litvinenko, who had been found in declining health at University College Hospital in London.
Litvinenko – a former Russian federal security services and KGB officer, and outspoken critic of President Vladimir Putin – died in 2006 after ingesting a rare radioactive substance.
