The secretive Wagner Group has a history of violence in Africa. In this episode, we ask why leaders are outsourcing security to an unaccountable army accused of murders, rapes and torture. We look into the crimes they're accused of committing, the governments they're keeping in power and the business deals making it all possible.

Aanu Adeoye, an Africa expert at London's Royal Institute of International Affairs, tells us about the propaganda machine behind Wagner. Keir Giles, a Russia specialist at Chatham House, explains just how intertwined the group is with the Russian state, and Dr Sorcha MacLeod, chair of the UN Working Group on the use of mercenaries, explains why the presence of groups like Wagner in unstable countries often makes things worse.
