Buhari weds new wife
I think there may be some misinformation here!
As of my knowledge cutoff, President Muhammadu Buhari of Nigeria is not married to a new wife. He has been married to his wife, Aisha Buhari, since 1989, and they have been together for over 30 years.
It's possible that you may be referring to a different public figure or celebrity who has gotten married recently. If you could provide more context or clarify who you are referring to, I'd be happy to try and help you with the information!
