Leaked emails damaging South Africa ANC party: Mantashe

South Africa's ruling African National Congress party is being damaged by leaked emails alleging fraud in the awarding of state contracts, the party's secretary general, Gwede Mantashe, said on Tuesday.

Allegations of government corruption have escalated this week after local media began reporting on more than 100,000 leaked emails they say show inappropriate interference in the issuing of lucrative tenders.
