During a discussion about gold dealers smuggling gold using private planes with the help of politicians, Zimbabwean gold dealer Ewan Macmillan referred to one individual as “comrade Chiwenga,” believed to be Vice President Constantino Chiwenga, and called him a “dunderhead.”

Al Jazeera has previewed snippets of its upcoming four-part documentary titled “Unveiling Zimbabwe’s Dark Secrets: Al Jazeera Exposes Looting, Plunder and Money Laundering,” which features a two-year investigation into corruption and money laundering in Zimbabwe involving senior government officials and their associates.

One of the key figures in the scam is Uebert Angel, President Mnangagwa’s appointed ambassador at large, as revealed in the trailer.

Macmillan also claimed that they control 90% of the Zimbabwe government. The release of the trailer has caused concern among government officials about how to handle the potentially damaging exposé.

In one of the excerpts, an undercover Al Jazeera journalist asks what will happen if their deals with “prophet” Uebert Angel, the leader of Spirit Embassy, are revealed, to which a person alleged to be Angel’s secretary responds that “anyone who exposes anything is thrown into prison.”
