CAPE TOWN — For years he seemed untouchable, protected by his family and business partners against allegations of severe graft.

But now Duduzane Zuma, son of the former South African president Jacob Zuma, is being charged for his alleged role in a high-level bribery scandal — further evidence, analysts say, that the ruling African National Congress is taking a tougher stance toward pervasive government corruption.

Duduzane Zuma, 33, will appear in the Specialised Commercial Crimes Court in Johannesburg this Monday, local newspapers reported Sunday. His lawyer, Rudi Krause, confirmed the court appearance, but said he did not yet know what the charges would be.

Police sources told City Press, a local newspaper, that the case related to a plot to bribe the former deputy finance minister, Mcebisi Jonas, in 2015.
