Members of the Senate Public Account Committee and the officials of the office of the Auditor-General for the Federation engaged in a heated debate on Tuesday with officials of the Nigerian National Petroleum Corporation over the agency’s alleged unremitted N4.06tn into the Federation Account. The Senate panel currently probing the allegation as contained in the 2016 report of the AuGF rejected the explanation offered by the NNPC and directed its officials to come up with more detailed explanations within the next seven days on how it expended the money on other items. The Office of the Auditor-General, had in its 2016 Audit report, alleged that the NNPC did not remit N4.076tn into the Federation Account from operational proceeds made between 2010 and 2016. The representative of the AuGF at the occasion, Olutoye Agesin, in his capacity as the Director of Public Accounts, clashed with Umar Ajiya who represented the NNPC GMD, as the Chief Finance Officer of the agency. The NNPC CFO, in his submissions before the committee, explained that the alleged unremitted N4.076tn was spent on other critical areas of operations which were not taken into cognizance by the AuGF office.
