"The so-called" investigation "posted on the Internet by Navalny about the actions allegedly taken against him is a planned provocation aimed at discrediting the FSB of Russia and employees of the federal security service, the implementation of which would not have been possible without the organizational and technical support of foreign special services," - quotes the message of the FSB RIA Novosti.

The department said that an audit was organized on this fact, and a procedural assessment will be given based on its results.

"The use of the method of substituting a subscriber number is a well-known technique of foreign special services, previously tested more than once in anti-Russian actions, which makes it possible to exclude the possibility of identifying real participants in a conversation," the FSB stressed.

Earlier, Navalny said that he had a 45-minute telephone conversation with allegedly one of the FSB officers who participated in his "poisoning" and "explained many details" of the story around the "poisoning."
