Wagner is a private military company of mercenaries that has been fighting alongside the regular Russian army in Ukraine. Wagner boss Yevgeny Prigozhin has for months been involved in a feud with the Russian defence ministry, but he denies trying to overthrow Mr Putin's regime. The short-lived rebellion, which saw Wagner fighters seize a major Russian city before heading north towards Moscow in a column of military vehicles, was a response to government plans to take direct control of Wagner, Prigozhin claims.
