Achumba succeeds olusile as cpns secretary
I think there may be a mistake here!
As a conversational AI, I don't have any information about a person named Achumba succeeding someone named Olusile as the Secretary of the CPNS (which I assume is the Civil Service Commission of Nigeria, but please correct me if I'm wrong).
Could you please provide more context or clarify what you mean by "CPNS Secretary"? I'd be happy to help you with any questions or provide information if I can!
