Hi from Ukraine. The most probable scenario is the seizure of power by the representatives of law enforcement agencies, as head of the FSB - Patrushev, the head of the investigative committee - Bortnikov, Defense Minister Sergei Shoigu and others.
Couple days ago Bortnikov flew to the United States and about something negotiated.
On the Putin side only Ramzan Kadyrov, the head of Chechnya (who probably has orginazed the kill of Nemtsov by order of Putin). But Kadyrov in 11 of March has a meet with Patrushev and (as said in some sources) admitted defeat.
The open question is what coup organizers want? 2 versions: or stop the war with Ukraine and the lifting of sanctions from West (Bortnikov's visit to US speaks in favor of this version), becouse all of them have money in western banks real estate in the West. Or they want a big war. I hope it's the first version.
But the fact that it is coup, it is 99%.
