Mmusi maimane wife celebrate 17 years of marriage

I think there may be some confusion here!

Mmusi Maimane is a South African politician who served as the leader of the Democratic Alliance (DA) from 2015 to 2019. I couldn't find any information about him celebrating 17 years of marriage with his wife.

If you meant to ask about someone else, please feel free to provide more context or clarify the question. I'll do my best to help!
