Presidency not vacant 2019 apc declares
I think I have found the context you're referring to!
On December 31, 2018, the All Progressives Congress (APC) in Nigeria issued a statement declaring that the presidency was not vacant, following rumors and speculations about the health of President Muhammadu Buhari.
At the time, President Buhari was on a 10-day medical leave in London, which sparked concerns about his ability to continue in office. However, the APC's statement, signed by its National Publicity Secretary, Lanre Issa-Onilu, insisted that the presidency was not vacant and that President Buhari was still in charge.
The statement read: "The attention of the All Progressives Congress (APC) has been drawn to the false and mischievous reports making the rounds that the presidency is vacant. We wish to categorically state that the presidency is not vacant and President Muhammadu Buhari is still the President of the Federal Republic of Nigeria."
The APC's statement was likely intended to reassure Nigerians and calm any concerns about the stability of the government, as well as to prevent any potential power vacuum or succession crisis.
