Prigozhin says Wagner will not sign any contract with Russian defence minister

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. Neither Shoigu nor Chief of the General Staff Valery Gerasimov have commented in public on the insults from Prigozhin, whose forces in May took the Ukrainian city of Bakhmut after a battle in which tens of thousands perished.
