With the acceptance, Abdullahi is expected to proceed on his voluntary retirement from Tuesday, August 18.
He had earlier written a letter dated August 3 to the President in which he notified Buhari of his desire to proceed on voluntary retirement from Tuesday.
Buhari’s approval of Abdullahi’s request was dated August 14 and personally signed by the President.
He thanked the NCS boss for his services to the county in the last six years.
The President’s letter was titled “Voluntary retirement from the Nigeria Customs Service.”
The approval read, “Dear, Alhaji D.I. Abdullahi. I write to acknowledge the receipt of your letter Ref. No. NCS/ADM/HQ/P. 35802 of 3rd August, 2015 conveying your decision to voluntarily retire from the Nigeria Customs Service with effect from Tuesday, 18th August, 2015.
“I note with appreciation your services to this nation, especially as the Comptroller-General of the Nigeria Customs Service in the last six (6) years.
“Accordingly, I hereby approve your voluntary retirement from the Nigeria Customs Service with effect from 18th August 2015.
“I wish you the very best in your future endeavours.
“Yours sincerely, Muhammadu Buhari.”
Abdullahi had, in his letter to the President, thanked him for the confidence and trust reposed on him since he (Buhari) was inaugurated on May 29.
He said by August 18, he would be six years in office as the Comptroller-General of the NCS.
He recalled that on assumption of office, he articulated six-point agenda which he vigorously pursued.
He said the agenda had positively impacted on the efficiency and performance of officers of the service and had drastically changed the negative perception of the service.
He listed the six-point agenda to include capacity building, introduction of e-Customs, enhancing productivity through improved welfare package, moral rebirth for discipline and integrity in service, collaboration and partnering with stakeholders and international organisations, as well as fostering understanding of the Service in the eye of the general public using an intensified and a well-coordinated public relations platform.
The NCS boss said under his watch, the revenue collection into various coffers of government increased drastically.
He said the Service’s average monthly collection in 2009 when he took over was about N29billion, adding that the average monthly collection is currently between N90billion and N100billion.
He hinged his decision to embark on voluntary resignation on the need to allow young bloods to takeover the mantle of leadership of the Service in order to sustain and improve on his legacy.
Abdullahi concluded, “While thanking Your Excellency and indeed Nigerians for the opportunity to serve and contribute my quota to the development of our fatherland, I wish to seek approval of Your Excellency to be allowed to retire voluntarily on 18th August 2015.
“This decision is taken with a view to allowing young bloods takeover the mantle of leadership of the Service in order to sustain and improve on my legacy.”
The President has yet to name Abdullahi’s successor at the time of filing this report.
