Mrs Winifred Oyo-Ita, Head of the Civil Service of the Federation has finally sent her resignation letter to Pres. Buhari.
She is currently under investigation by EFCC over alleged N3billion contract scam, abuse of duty tour allowance, money laundering, among others.
Last week, her international and diplomatic passports were seized by the agency and she has been restricted to the country pending the conclusion of investigation.
Although she is hospitalized after complaining of being ill, sources said security operatives had been deployed to monitor her movement in the Abuja hospital.
EFCC in a recent development questined Oyo-Ita over accusations that she used front companies to get contracts when she was a permanent secretary before her nomination as head of service by Buhari in 2015.
It was also inscribed that N600 million was tracked to the account of one of her aides who has been questioned by the anti-graft agency and released. However, Oyo-Ita has denied the allegations.
