No vacuum in presidency after buharis vacation extension spokesman

I think there may be a bit of a language barrier or misunderstanding here!

It seems like you're trying to ask a question, but the sentence is a bit unclear. Here's my attempt to decipher it:

Are you asking if there will be no vacuum in the presidency after President Muhammadu Buhari's vacation extension, according to his spokesman?

If that's correct, I'd be happy to help you with the answer. However, if I'm still misunderstanding the question, please feel free to rephrase or provide more context!
