The CIA Africa Review for September 1978 at pages 12-18 covers “The Economic Stake of the Kenyatta Family”. I have embedded it below for downloading in its recently declassified form from the CIA CREST database at the Agency online FOIA reading room. This report is related to the story in The Standard noted in my post “Standard covers newly declassified CIA report on Kenyatta family wealth acquisition during Jomo’s rule”.  I thought you should read it in full for yourself:

1 Sept 78 Kenyatta wealth – The Royal Family Jewels

The report discusses the acquisition of vast acreage, in significant part grabbed through control of British funding for the buyout of former colonists, along with stakes in large Western companies in Kenya such as Lonrho and Ford Motor Company, along with mines and other enterprises. It also says that Mama Ngina and Sister Margaret were at the time probably the largest traders in charcoal and illicit ivory.

The CIA observed that Kenya appeared to be headed to balance of payments problems which would necessitate austerity measures which could trigger political instability. Resentment was already high about the cost of the Kenyatta family’s self-dealing. The risk was exacerbated by the desire of the incoming Moi faction to deal themselves in.
