Recent cases include the gang rape of eight women in Krugersdorp, which has been blamed on illegal foreign miners, and Eswatini spokesperson Alpheous Nxumalo's comment that “South Africa is infested with a cancer of criminality from head to toe”.

Clayson Monyela, deputy director-general for public diplomacy, said Nxumalo had insulted South Africans.

Monyela joins host Mike Siluma to discuss these issues.
