It is impossible for a person poisoned by Novichok to recover, which indicates the existence of a plot against Russia.
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.
Recurring pro-Kremlin disinformation narrative about the poisoning of Alexey Navalny. The use of a chemical nerve agent of the Novichok group in the poisoning of Alexei Navalny was established beyond any doubt by a Bundeswehr laboratory. In September 2017, the Organisation for the Prohibition of Chemical Weapons (OPCW) confirmed the full destruction of the 39,967 metric tons of chemical weapons possessed by Russia, but Novichok was never declared to the OPCW and wasn’t included in the Chemical Weapons Convention until 2019. As far as Vil Mitzayanov is concerned, after the poisoning of Sergei and Yulia Skripal with Novichok in Salisbury in 2018, he said that “many countries could have had test samples, but production was only refined in the U.S.S.R. and Russia” and that Russia had to be behind the attempt because it “is the country that invented it, has the experience, turned it into a weapon... has fully mastered the cycle”. There are also other cases following the same trend of disputing Navalny's poisoning and the use of Novichok by Russian state operatives, which can be found here and here.
