The Senate on Thursday commenced investigation into the alleged unauthorised spending of N567bn being the cost of tax collected by the Nigerian Customs Service and the Federal Inland Revenue Service from January 2005 to July 2015.
A non-governmental organisation, Legislative Watch, dragged the two Federal Government agencies to the Senate through a petition that was sent to the Senate President, Bukola Saraki, on 13 August, 2015.
The Senate, thereafter, referred the petition to its Committee on Ethics, Privileges and Public Petitions.
A document from the Federal Ministry of Finance, presented to the committee by the petitioner, indicated that the average monthly collection cost of the NCS was N2.5bn which put the total amount not remitted by NCS for 126 months (January 2005 to July 2015) at N315bn.
