MOSCOW, December 23. /TASS/. Western countries have given no evidence to prove allegations about Russian blogger Alexey Navalny’s possible poisoning, Russian President Vladimir Putin said on Thursday.

"You speak about a man who was allegedly poisoned. We have issued numerous official inquiries from the Russian prosecutor’s office asking for any documents proving the poisoning. Not a single paper, not a single evidence of this Novichok, or whatever you call it," he said during his traditional end-of-the-year news conference answering a question from a BBC correspondent.

According to the Russian leader, Moscow suggested sending Russian specialists "there to work together." "I personally told the French president and the German chancellor: Let our specialists work, let us take sample, check grounds to open a criminal case. Nothing in response. Nothing," he said, describing the contacts on this matter.

"Stop talking about it. Let us turn over this page, if you have nothing to tell us," he noted.

Alexey Navalny was rushed to a local hospital in the Siberian city of Omsk on August 20, 2020, after collapsing on a Moscow-bound flight from Tomsk. He fell into a coma and was put on a ventilator in an intensive care unit. On August 22, he was airlifted to Berlin and admitted to the Charite hospital. On September 2, the German government claimed that the blogger had been affected by a toxic agent belonging to the Novichok family. Russia’s authorities pointed out that no poisonous substances had been detected in Navalny’s system prior to his transfer to Berlin and repeatedly expressed readiness for all-round cooperation to investigate this case.
