The Office of the Special Prosecutor (OSP) has summoned the Commissioner-General of the Ghana Revenue Authority (GRA), Anthony Sarpong, and two senior officials to appear before investigators in connection with the ongoing probe into the SML Ghana contract controversy.

Sources indicate that the summons follows the arrest of the GRA’s Acting Head of Legal and is linked to alleged contradictory statements and a letter the three officials are suspected of instructing her to issue to lawyers representing SML Ghana.

Those invited include Mr. Sarpong, Assistant Commissioner in charge of Finance, Celestine Annan, and Technical Assistant to the Commissioner-General, Kenneth Agyei-Duah.

This is reportedly the second time Mr. Sarpong and Ms. Annan have been invited by the OSP, after earlier testimonies appeared inconsistent with the contents of the controversial letter, believed to have been issued in mid-October at SML’s request.

Both Mr. Sarpong and Mr. Agyei-Duah previously worked with KPMG, the auditing firm engaged by former President Nana Addo Dankwa Akufo-Addo to review SML Ghana’s operations.

The development comes after the OSP confirmed on Monday, November 3, 2025, that the GRA’s Acting Head of Legal had been arrested and placed under investigation for alleged corruption, obstruction of justice, and other corruption-related offences tied to the SML deal.

The GRA–SML Ghana contract, which engaged SML to provide revenue assurance services in the petroleum and minerals sectors, has been at the centre of controversy over claims of inflated costs, procurement breaches, and lack of value for money.

The OSP, led by Special Prosecutor Kissi Agyebeng, has since widened its investigations to cover senior figures at both the GRA and the Ministry of Finance.

Mr. Agyebeng recently revealed that the OSP intends to file charges by the end of November 2025 against several individuals implicated in the scandal, including former Finance Minister Ken Ofori-Atta and two former GRA Commissioner-Generals, Dr. Ammishaddai Owusu-Amoah and Emmanuel Kofi Nti.

He stressed that the investigation aims to “safeguard public resources and ensure accountability in the management of state contracts.”
