Investment banker John Ngumi has detailed his role in several major corporate and government-linked transactions, including the Sh6.2 billion Telkom Kenya deal, Safaricom, Kenya Airways and other high-value investments.

Ngumi says he faced intense scrutiny over the Telkom transaction and challenged attempts to recover money from him, arguing that the payment he received reflected professional work undertaken on the deal.

He also described conflicts with powerful officials and political actors over corporate decisions.

His account offers an insider view of how major Kenyan transactions are negotiated, how advisers interact with government and how politically sensitive business deals can expose executives and financiers to investigations years later.
