Throughout history there have been many high-profile cases of personalities behind the scenes directing power with or without the consent of the person who would have had the charge to exercise it.
In ancient Rome: Seneca and Nero
In France: Richelieu / Mazzarino versus their king
In the US: Eleanor Roosevelt versus Franklin Delano Roosevelt
In every day's life:
wife versus husband
secretary versus head of the department
assistant professor versus Professor
And in your life would you prefer to act as a gray eminence or as a head?
Is there in the governance of your country a similar problem?
