Putin Struggles to Maintain Control Over Mercenary Outfit Amid Power Struggle

Putin is reluctant to punish Yevgeny Prigozhin, commander of the Wagner Group mercenary outfit, for criticizing Russian military leaders because he needs Prigozhin's support.
Prigozhin accused Russian Defense Minister Shoigu of depriving his fighters of ammunition and support in Ukraine.
The Wagner Group has fought effectively for Russia in Ukraine, Africa and the Middle East despite suffering major losses.
The Russian Defense Ministry wants the Wagner Group and other irregular units to sign contracts by July 1 to centralize control over them.
Former Kremlin officials warn Putin could face challenges to his power if Russia loses the war in Ukraine.
