MOSCOW (Reuters) -Russia's most powerful mercenary said on Sunday that his Wagner fighters would not sign any contract with Defence Minister Sergei Shoigu, publicly refusing an attempt by the defence ministry to bring his fighting force under its sway.
Yevgeny Prigozhin, the founder of the Wagner group, has repeatedly attacked President Vladimir Putin's top military brass for what he casts as treachery for failing to fight the war in Ukraine properly.
