On September 11, the transport department of the Ministry of Internal Affairs for the Siberian Federal District reported that one of the six women who accompanied Navalny on a trip to Siberia, on August 20, avoided giving explanations.

According to the police, we are talking about Marina Pevchikh, "permanently residing in the UK."

In the media, she is called Maria Singers.

According to the investigation, on August 22, she flew to Germany.

Its location is being established.

During a press conference, the RT journalist asked the official representative of the German government, Steffen Seibert, whether the German Cabinet of Ministers knew where the Singers were and how her departure was assessed.

“I can't tell you anything about this,” Seibert said.

The journalist asked a clarifying question whether there was any special permission, by virtue of which Singers entered Germany, noting that the FRG should give an assessment, since "the other five gave themselves to be questioned."

“I am not familiar with this case and will not speak out on it,” the Interior Ministry spokesman replied in turn.

On August 20, the plane with Navalny urgently landed in Omsk due to a sharp deterioration in his health.

He was later transported to a Berlin hospital. 

On September 2, the German government announced that the tests conducted revealed a substance from the Novichok group in Navalny. 

Russian Foreign Minister Sergei Lavrov said that Western partners in the situation with Navalny went beyond reason. 

The minister noted that Russia does not yet have legal grounds to open a criminal case on this incident, and that is why on August 27 the Prosecutor General's Office requested legal assistance from the FRG.
