Per a translator I heard, Putin compared this to 1917. Stated this is intrigue. That Russia is fighting a grave threat for its future. This is a “mortal fight,” which his government is fighting on behalf of the Russian people. That orders have been given to liquidate the leaders of Wagner.
If you’re still seeing the speech going on, I believe it started to loop thereafter, but it is over now.
Putin has little choice but to back his MoD and Chief of Staff of the Armed Forces. A coup against them is a coup against Putin. Hard to figure where this ends. Is there a way out for Putin other than military confrontation in Moscow?
