British police say a third Russian has been charged in absentia with the 2018 Novichok murder attempt on former double agent Sergei Skripal, claiming that the three suspects were military intelligence operatives.
The attack on Skripal, who sold Russian secrets to the UK, caused the most significant row between Moscow and the West since the Cold War, leading to the tit-for-tat expulsion of dozens of diplomats after London pointed the finger of blame at the Kremlin.
Russia has consistently rejected any involvement in the matter, casting the accusations as anti-Russia propaganda.
Skripal and his daughter Yulia were found unconscious on a public bench in the southern English city of Salisbury in March 2018. Along with police officer Nick Bailey, who went to Skripal's house to investigate, they were left seriously ill in hospital from exposure to the military-grade nerve agent.
The three eventually recovered but Salisbury resident Dawn Sturgess died from Novichok poisoning after her partner found a discarded counterfeit perfume bottle, which police believe had contained the poison.
In September 2018, British prosecutors charged two Russians, then identified by the aliases Alexander Petrov and Ruslan Boshirov, with conspiracy to murder Skripal and the attempted murder of Yulia and Bailey.
