David Tennant to star in new ITV drama Litvinenko
Written by George Kay, the four-part drama will explore the death of former Russian Federal Security Services and KGB officer Alexander Litvinenko, who was found dead from polonium poisoning in November 2006.
The murder led to one of the most dangerous and testing investigations in the history of the Metropolitan Police.
The drama highlights the painstaking work of the Scotland Yard officers who dedicated ten years of their lives to discover who was responsible.
