Prigozhin has been getting more and more scathing of the government.

> The Ministry of Defense is deceiving the public and telling the story that there was aggression on the part of Ukraine for 8 years, and they were going to attack us together with all of NATO. Ukraine did not attack the civilian population, only the positions of the Russian army

> No one killed 60 leopards, this is complete total nonsense, now the Russian army is retreating in the Zaporozhye, Kherson directions, - Prigozhin.
> The Armed Forces of Ukraine are pushing through the Russian army, we are washing ourselves with blood, no one gives reserves, there is no control.
> Zelensky, when he became president, was ready for agreements. All that had to be done was to get down from Mount Olympus, go and negotiate with him, 
> What was the war for? The war was needed for Shoigu to receive a 'hero star'. The oligarchic clan that rules Russia needed the war. The war was needed to install Medvedchuk as president of Ukraine.

I predict that he is going to fall out of a window or brutally stab himself to death while shaving in not long.
The Russian government has been trying to make third party militants sign contracts with the RU MOD, the Chechens have but Prigozhin kicked up a fuss about it and I don't think Wagner has yet.
