According to The Insider, both publications point out that the fact of negotiations between German and Bulgarian doctors indicates that similarities were found in both incidents at Charité.
Der Spiegel writes that doctors assume that the oppositionist was exposed to a substance from the organophosphate family - Gebrev was poisoned the same way. These include insecticides and nerve toxins such as sarin and Novichok.
According to German doctors, the clinical results of Navalny's examination indicated that it was poisoning that took place. The Charité said that a substance from the group of active ingredients of cholinesterase inhibitors could cause intoxication. But experts still cannot determine what kind of substance it was.
Recall that Emelyan Gebrev and his son Hristo felt unwell in April 2015 while in Sofia. After that, the businessman fell into a coma. The media, referring to experts from the University of Helsinki, wrote that the businessman and his son could have been poisoned by Novichok.
In November 2019, The Insider reported that Russian military intelligence officers could be involved in the poisoning of a Bulgarian businessman, including Sergei Fedotov (according to media reports, his real name is Denis Sergeev), who could also be involved in the poisoning of Sergei Skripal , a former GRU officer.
Recall that Navalny was hospitalized in Omsk after he felt bad during a flight from Tomsk to Moscow. After an emergency hospitalization, the oppositionist fell into a coma. Russian doctors insisted that no toxic substances were found in the patient's body, and the version of the poisoning was worked out by them on the first day, but remained unconfirmed.
A number of countries - the US, France, Germany, the UK and the EU - have called for an investigation into the politician's possible poisoning. The Kremlin, on the other hand , said that at the moment it sees no reason to initiate a criminal case, and called the charges of the attempted murder empty.
