Abubakar disclosed this to State House reporters on Saturday shortly after meeting with the President.
Though he did not disclose the reason for the resignation, Abubakar said he discussed with Tinubu who understood with him.
On his visit to the Presidential Villa, Abubakar said he came to visit Tinubu to “brief Mr President on issues and today is no exception.”
“After the briefing, I tendered my resignation and Mr President graciously approved and accepted the resignation.”
