The Presidency has criticised the ranking of President Goodluck Jonathan by a U.S. website – RichestLifestyle.com – as the sixth richest African President with an estimated net worth of $100 million.

In a pressed statement released on Wednesday, the special adviser to the President on media and publicity, Reuben Abati, said the ranking was totally unwarranted.

Abati said the inclusion of President Jonathan in the publication titled “Africa’s Richest Presidents 2014” was just another attempt to unjustifiably portray the President as a corrupt leader and incite public disaffection against him.

“We categorically assert that there is no factual basis for ranking President Jonathan as the sixth richest African Head of State with a net worth of about $100 Million U.S. Dollars,” the President’s spokesman said.

He added, “As is well known, President Jonathan has never been a businessman or entrepreneur, but a life-long public servant. The President has held public office since 1999 and has regularly declared his assets as required by Nigerian laws. He has had no personal income since 1999 other than his official remuneration as deputy governor, governor, vice president, acting president and president which are matters of public record.”

Other African presidents and kings on the list include Jose Eduardo dos Santos of Angola ( $20 billion); Mohammed VI of Morocco ( $2.5 billion); Teodoro Obiang Nguema Mbasogo of Equatorial Guinea ($600 million) and Uhuru Kenyatta of Kenya ($500 million).

Others are Paul Biya of Cameroon ($200 million); King Mswati III of Swaziland ($100 million – the monarch shares the number 6 spot with President Jonathan), Idriss Deby of Chad ( $50 million) and Robert Mugabe of Zimbabwe ($10 million).
