A Leaked memo signed by Tunde Fowler, erstwhile chairman of  Federal Inland Revenue Service, FIRS, showed he asked for his tenure to be renewed by President Buhari but it was denied.
In the letter with reference number FIRS/EC/CWOSGF/0476/19/006 and dated December 9th 2019, Fowler, who is a childhood friend and former classmate of Vice President Yemi Osinbajo, reminded the President that his tenure had elapsed and would love for it to be renewed. .

The letter which he wrote through the office of the Secretary to the Government of the Federation, Boss Mustapha, reads in part “I write to notify the Secretary to the Government of the Federation that my first tenure as the Executive Chairman of the FIRS ends today, December 9, 2019. In view of the above, I wish to present myself for re-appointment for a second term. This is consistent with provisions of the FIRS Establishment Act 2007 and would grant me the opportunity to consolidate and build on the achievements we have recorded in the past four years. .
