There are western intelligence reports that Prigozhin has been giving information on Russian troop locations to the Ukrainians to stop them hitting his own forces and also another one saying Putin intends to arrest Prigozhin for treason.

I'm not sure how true this is, it seems like they are trying to create a fissure between Wagner and the Russian army and undermine the Russian war effort as a whole as Wagner is pretty popular amongst pro-Russians online at least.

I think if Putin wanted to remove Prigozhin he would do it in the same way that Hitler got rid of Rommel, he would kill him in secret and them make him a war hero.
