#8:. Mo Ibrahim, $1.1 billion – Sudanese/British, Mobile Telecoms, Investments
Sudanese-born Mo Ibrahim founded Celtel, an African mobile phone company, which he sold to Kuwait’s MTC for $3.4 billion in 2005.
He is the founder of the Mo Ibrahim Foundation which promotes good governance in Africa and awards the annual Mo Ibrahim prize for Achievement in African Leadership – a lifetime award of $5 million given over 10 years to retired African presidents who were transparent and served terms set by their countries’ constitutions.
Nelson Mandela was an honorary recipient. Here’s what Ibrahim said about presidents who just won’t go away: “Power is very seductive. If you control a country for some time, then there comes a point where you feel indispensable.”
