The Controversial Rise of Evgeny Prigozhin in Russian Politics and Military Affairs.

Yevgeny Prigozhin, the boss of the Wagner Group, has raised the stakes in his feud with Russia's Defense Ministry, according to the UK Ministry of Defence. Prigozhin delivered a contract of his own drafting to the ministry, which the MoD said was "another deliberate effort to undermine the authority of the official military authorities." The move comes after Russian Defense Minister Sergei Shoigu ordered Prigozhin to sign contracts directly with the defense ministry by July 1, which was endorsed by Russian President Vladimir Putin.
