He made this known while speaking at a dinner organised in honour of President Muhammadu Buhari and himself at the State House Banquet Hall.
Osinbajo, who also represented President Buhari at the dinner, said: “Something interesting happened earlier today; I am a lawyer and a law teacher and I like to test and interrogate legal scenarios.
“At one minute past midnight today, the four-year term of the President and I ended by effluxion of time.
“So, from one minute past 12 of last night, May 29 to about 10:30 am when we were sworn in for a second term there was no President or Vice President.
“Interestingly nothing went wrong, all was okay; when such a situation arises, it is the Senate President who acts as President.
“So, when I arrived at Eagle Square this morning, some may have noticed that the Senate President Bukola Saraki and I were enjoying a joke.
“He said to me jokingly `you better be careful you know I am the acting President now’; so, we thank the Senate President for not doing anything funny.’’
