Any laboratory in the world is able to produce this substance [Novichok] as Vil Mirzayanov has revealed in his book all the needed formulas to produce this toxic agent.
The Kremlin has repeatedly denied allegations that security services used the Novichok military poison.
The Russian side has repeatedly expressed its willingness to cooperate since it appealed to the competent authorities of the Federal Republic of Germany with a request to present the revealed facts of poisoning. It was quite expected that Russia’s requests would not be satisfied, since their presence would have put a glorious end to the joint venture of the Western special services.
Conspiracy theory. Recurring pro-Kremlin disinformation narrative about Alexei Navalny alleging that he was sponsored by anti-Russian forces.
There are no grounds for connecting either the US or UK or any Western special services to Navalny's poisoning. The activist fell ill on a 20 August flight from Siberia to Moscow. Initially hospitalized in Omsk, he was transferred to the Charité hospital in Berlin at the request of his family. Clinical findings at the Charité hospital indicated that Navalny was poisoned with a substance from the group of cholinesterase inhibitors. Subsequent toxicological tests provided unequivocal evidence of a chemical nerve agent of the Novichok group in the blood samples of Alexei Navalny.
