Polonium-210 was in London before the Russian citizens accused of poisoning Aleksandr Litvinenko arrived there, and evidence pointed to his patron Boris Berezovsky, Moscow has said, citing a German probe.
Russian prosecutors said this was proven by the UK's own data, which it shared with Berlin.
The claim comes from the Russian Prosecutor General's Office, which
shared documents relating to several high-profile crimes that happened on British soil. Russia says it was unsatisfied by how Britain handled them. Moscow officials pointed to what they see as flaws in relevant probes on the British side, and have accused UK authorities of failing to conduct proper investigations.
One of the cases was the poisoning of Aleksandr Litvinenko, a former Russian intelligence officer and close associate of fugitive Russian tycoon Boris Berezovsky. The standing narrative in the case in Britain is that Litvinenko was poisoned with Polonium-210, a rare radioactive substance, by two Russian citizens, Dmitry Kovtun and Andrey Lugovoy.
Neither stood trial for the crime, but British officials insist that there was no other credible explanation for Litvinenko's killing.
