Ngina Kenyatta, the widow of Kenya’s first President Jomo Kenyatta, has become Kenya Power’s fourth biggest shareholder in the power utility.

According to Kenya’s Business Daily, filings with the Capital Markets Authority in that country show that President Uhuru Kenyatta’s mother holds 2.2 million shares in the firm or a 0.11 percent interest.

Not much is known about Mama Ngina but her Kenya Power interest is now worth Sh37.7 million ($449, 602).

The past first lady received a dividend of Sh1.1 million ($13, 118). Kenya Power announced a final dividend of Sh0.50 for the year to June 2012.

Mama Ngina controls a business empire that is connected to famous and profitable products and blue chip firms.

These involve Commercial Bank of Africa (CBA), which is Kenya’s biggest non-listed bank with assets worth Sh100 billion ($1.2 billion). Last year, the bank reported a net profit of Sh2.6 billion ($31 million).

According to the report, the bank ranks as Kenya’s ninth largest with a market size index of 4.08 percent.
