Richest african aliko dangote celebrates diamond jubilee

I think there may be some confusion here.

Aliko Dangote is indeed a Nigerian businessman and the richest person in Africa, according to Forbes. However, I couldn't find any information about him celebrating a diamond jubilee.

A diamond jubilee typically refers to a 75th anniversary or a celebration of 60 years of a significant event or milestone. It's possible that you may be thinking of Queen Elizabeth II, who celebrated her Diamond Jubilee in 2012, marking 60 years on the British throne.

If you could provide more context or clarify what you mean by "diamond jubilee" in relation to Aliko Dangote, I'd be happy to try and help you further!
