President Buhari has publicly stated that the presidency of Nigeria has been quite tough on him and that he is eager to go.

This is understandable in a very complex country as Nigeria that still has a young democracy, worsening insecurity and increasing poverty. 

To ensure that Nigerians get the best from his administration in its last days, we request for President Buhari to voluntarily resign so that his second in command can complete his government with restored and much needed tenacity, for the sake of all Nigerians.
