Officials at the presidency said Mr. Ogunlesi had undergone security screening and his appointment is to be announced in the coming days.
According to reports, Mr. Ogunlesi, who is one of Nigeria’s most active Twitter users, was clearly in favour of Mr. Buhari’s election in the 2015 general elections.
He will be the Buhari administration’s social media anchor, a role played by Reno Omokiri for former President Goodluck Jonathan.
On his twitter handle, Mr. Ogunlesi describes himself as a poet, photographer, and fiction writer.
Before his appointment, he was a freelance writer, contributing articles to various publications, mostly abroad.
Mr. Ogunlesi, who trained as a pharmacist, worked as Features Editor for the defunct 234NEXT newspapers. In 2009 he was awarded the Arts and Culture prize in the annual CNN Multichoice African Journalism Awards.
He won the CNN award again in 2013 in another category. He was also shortlisted for the inaugural PEN/Studzinski literary prize.
