The widow of Yevgeny Prigozhin, the mercenary who died in an unexplained plane crash in August two months after leading an unsuccessful mutiny, has officially changed her last name, the RBK news agency reported, citing registration data. Lyubov Prigozhina has reverted back to her maiden name Kryazhevaya, RBK said. Prigozhin had three children but RBK did not know whether they too had changed their family names. Prigozhin’s mutiny was the greatest challenge to Vladimir Putin during his 24-years in power. The Russian president called his rebellion “treason” and a “stab in the back,” leading many experts to predict the mercenary’s demise.
