"The investigative department [of the ministry]... is preparing an additional request for legal assistance to the competent authorities of Germany. This request will include a petition on a possibility of the presence of investigators of the Russian internal affairs bodies conducting an inspection on this fact, and a Russian expert (specialist) when German colleagues carry out investigative actions with Navalny, doctors and experts, including when receiving explanations, with the possibility of asking clarifying and additional questions," the statement said.
On Monday, the Charite hospital in Berlin, where Navalny is being treated, announced that the patient's condition had improved and he was woken up from coma.
Navalny felt unwell during a Russian domestic flight on 20 August and was initially treated in the Siberian city of Omsk, where the plane made an emergency landing. Two days later, once the doctors established he was fit for cross-border aerial transportation, the 44-year-old was flown to the German capital for further treatment.
The German doctors initially stated they had found traces of a substance from a group of cholinesterase inhibitors in his system, before claiming that it was Novichok poisoning.
In response, German Foreign Minister Heiko Maas said that Berlin could share the information about Navalny, but that it was a multistage process.
Last week, the German government said traces of a nerve agent from the Novichok group were detected in Navalny's system. Moscow said Russian doctors found no toxic substances before he was transported to Germany and that Berlin has provided no evidence to support its claims.
