Statesman and founding member of the New Patriotic Party (NPP), Dr Nyaho-Tamakloe, has called for full transparency in investigations into the alleged bribery scandal involving former Tema Oil Refinery (TOR) Managing Director Asante Kwaku Berko and other Ghanaian officials.
Dr Nyaho-Tamakloe said he was confident that investigations by Ghana’s security agencies, including the Economic and Organised Crime Office (EOCO) and the Office of the Special Prosecutor (OSP), would shed further light on the allegations contained in the United States case.
His comments follow the ongoing prosecution of Berko, a dual Ghanaian-American citizen and former executive at Goldman Sachs, in the United States over allegations that he bribed Ghanaian officials to secure approvals for a power plant project.
Berko was extradited from the United Kingdom to the United States in July 2024 to face charges under the Foreign Corrupt Practices Act (FCPA) and money laundering laws. U.S. prosecutors have alleged that he and his co-conspirators made corrupt payments to Ghanaian officials in connection with a power plant deal involving Turkish energy company Aksa Enerji.
Speaking on Ghana Tonight on TV3 on Monday, August 10, 2026, Dr Nyaho-Tamakloe urged Ghanaian investigators to pursue every individual named or implicated in the case, regardless of their political connections.
“The most important thing is that the case that was held outside the borders of this country has mentioned names, and these names should not be withheld,” he said.
He expressed confidence that the ongoing investigations by EOCO and the OSP would help establish the facts surrounding the allegations.
“If EOCO and OSP have been named for finally going into these, I believe strongly they would agree with what has been said in the US court and those involved; there shouldn’t be any person who should be shielded,” he stressed.
Dr Nyaho-Tamakloe said Ghana must ensure that the investigation did not become selective, arguing that anyone found to have participated in wrongdoing should be held accountable irrespective of political affiliation.
“In this allegation, we demand transparency and there shouldn’t be any selective justice whatsoever,” he stated.
Background
Asante Kwaku Berko, a former executive director in the investment banking division of Goldman Sachs International and former Managing Director of the Tema Oil Refinery, is facing charges in the United States over an alleged bribery and money-laundering scheme linked to the development and financing of a power plant in Ghana.
According to U.S. court documents, the alleged scheme took place between approximately December 2014 and March 2017, when Berko was involved in managing a deal between a Turkish energy company and the Government of Ghana for the construction and financing of a power plant.
U.S. prosecutors allege that Berko and his co-conspirators made payments to Ghanaian government officials to help secure approvals for the project. The alleged payments were subsequently concealed through mechanisms including shell companies, false invoices and bank transactions, according to the indictment.
The U.S. Department of Justice said Berko was extradited from the United Kingdom to the United States in July 2024 to face charges of conspiracy to violate the FCPA, substantive FCPA violations and conspiracy to commit money laundering.
The case has since proceeded to trial in federal court in Brooklyn. Reporting from late July 2026 indicated that the trial had begun, with prosecutors alleging that Berko participated in a scheme to bribe Ghanaian officials, while his defence challenged the government’s case.
The allegations have also raised questions in Ghana about whether officials who may have been involved in the alleged scheme will be identified and investigated.
Dr Nyaho-Tamakloe’s call therefore places renewed pressure on Ghanaian investigative authorities to establish the facts, identify all persons implicated and ensure that any prosecution is conducted transparently and without political favouritism.
