This award-winning current affairs show finishes up its latest series tonight and sees Kiki King in Mozambique where she investigates the disturbing phenomenon known as 'sex for grades', where teachers force their female pupils to have sex with them in return for better grades - or even their deserved grades. As King discovers, the Mozambican Ministry of Education has found that 70 per cent of schoolgirls are either facing this kind of harassment or witnessing it. Horrifying stuff, but once again, Unreported World shines a light on something that is not being talked about in mainstream media.
