Why SA lambasted Eswatini government spokesperson for his comments on crime

This week on Sunday Times Politics Weekly we look at the strained relationship between SA and its neighbours due to an influx of foreigners accused of crime.
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.
