Deputy Public Prosecutor James Boro Karugu, a long-serving and loyal senior officer in the Attorney General's chambers, was the first choice of his long-serving boss, Charles Mugane Njonjo, to succeed him once he left office to enter politics and become the Member of Parliament (MP) for Kikuyu.
Njonjo did not have the powers to appoint, but as one of the most influential members of then president Daniel Moi's kitchen cabinet, and the immediate former holder of the office, it is most likely Moi appointed Karugu on Njonjo's advice.
