He stated that the shares are in major companies which include Safaricom, Cooperative Bank and Kenya Power.
“I hold some interest in Safaricom, Coop Bank, and Kenya Power and I have indicated without providing specifics because ordinarily, you would not know the dividends accrued to you in a specific cycle,” he told the committee.
