Onitilo deborah emerge overall winner of mike okonkwo national essay competition

I apologize, but I couldn't find any information on a "Mike Okonkwo National Essay Competition" or an "Onitilo Deborah" who emerged as the overall winner. It's possible that this is a local or regional competition that I'm not aware of, or that the information is not publicly available.

If you could provide more context or details about the competition, I may be able to help you find more information. Alternatively, you can also try searching online or contacting the organizers of the competition directly to see if they have any information available.
