Equatorial Guinea, 2004 — dissident coup conspiracy

Equatorial Guinea (GNQ)Central Africa, AfricaMarch 7, 2004

Event Summary

This entry is coded 7 March 2004, corresponding to the 2004 Equatorial Guinea coup attempt, widely known as the Wonga Coup, against President Teodoro Obiang Nguema Mbasogo. A group of mercenaries organized by mainly British financiers and led by former Special Air Service officer Simon Mann planned to overthrow Obiang and install the exiled opposition politician Severo Moto, prosecutors alleging that Moto was to be made president in return for preferential oil rights in the oil-rich state. On 7 March 2004 Zimbabwean police impounded a Boeing 727 at Harare airport that had flown in from South Africa carrying dozens of former soldiers, most of them ex-members of South Africa's disbanded 32 Battalion, who were waiting to load weapons; Mann and colleagues were arrested near the runway.

Around the same time a second group led by Nick du Toit was arrested inside Equatorial Guinea. The plot drew international attention when Mark Thatcher, son of former British Prime Minister Margaret Thatcher, was later convicted in South Africa of helping finance it. Mann was sentenced to 34 years and later pardoned.

The 7 March 2004 coding matches the Harare arrests exactly.

Sources

The 2004 Equatorial Guinea coup attempt, also known as the Wonga Coup, failed to replace President Teodoro Obiang Nguema Mbasogo with exiled opposition politician Severo Moto, as mercenaries organised by mainly British financiers were arrested in Zimbabwe on 7 March 2004 before they could carry out the plot.
