WINIFRED Oyo-Ita, the head of service on Monday in a letter to President Muhammadu Buhari said she would be retiring from civil service with immediate effect.
According to reports, the head of service was being probed over an alleged contract scam amounting to N3billion and has been pressurized by family members to resign.
Since the news of the probe went public, she has consistently denied her involvement in any scam, until Sunday when she eventually sent in her resignation letter.
“Mrs Oyo-Ita has sent in her letter of retirement,” said a family member.
It has been previously alleged that the probe was borne out of a misunderstanding with Abba Kyari but Oyo –Ita has vehemently refuted the insinuations.
The Economic and Financial Crimes Commission (EFCC) recently questioned Oyo-Ita over allegations that she used proxy companies to get contracts when she was a permanent secretary before her appointment as head of service in 2015.
Prior to her invitation by the anti-graft agency, the sum of N600 million was traced to the account of one of her aides, who has been interrogated by the EFCC but was later released.
Oyo-Ita has refuted the allegation to defraud the state, claiming the money was meant for death benefits of staff.
The president is yet to take a final decision on the resignation letter.
