Achievement as Chief Executive of Ghana COCOBOD
As Chief Executive of Ghana Cocoa Board, he had through the support of the Government of Ghana initiated several interventions aimed at enhancing sustainable cocoa production.
Some of these interventions include the aggressive cocoa rehabilitation programme and the youth in cocoa programme which has so far motivated over 30,000 young men and women into cocoa farming.
Mr. Opuni’s tenure at COCOBOD was engrossed in several allegations of corruption and mismanagement of the cocoa sector, with his critics accusing him of running down the critical sector; which generates revenue for the country and employs millions of Ghanaians.
In April 2016, the General Agriculture Workers Union (GAWU), and the Industrial Commercial Workers Unions (ICU), launched a scathing attack on the leadership of COCOBOD, accusing its Chief Executive Officer, Dr. Stephen Opuni of presiding over corruption.
GAWU and ICU said corruption at COCOBOD, headed by Dr. Stephen Opuni was affecting the production of cocoa in the country.
But some staff of COCOBOD at the time jumped his defence, insisting that, Dr. Opuni has not caused any disaffection within the ranks of COCOBOD as ICU and GAWU were alleging.
The Staff of the company thus served notice of withdrawing from the two unions, citing a growing mistrust between workers of COCOBOD and the unions.
Dr. Opuni was removed from office when President Nana Addo Akufo-Addo took office in 2017.
His bank accounts were frozen following investigations into some contracts he signed during his tenure.
The Economic and Organised Crimes Office (EOCO) has been investigating him since he left office.
