Nepotism
From dKosopedia
Nepotism is the practice of favoring family members for appointment to government office or other positions of responsibility.
For example, Simone Ladeen, daughter of neo-conservative columnist Michael Ladeen, was one of many children of prominent Republican elites who were given positions of authority beyond their competence in the Coalition Provisional Authority (CPA) in Iraq. See Rajiv Chandrasekaran's 2006 Imperial Life in the Emerald City: Inside Iraq's Green Zone, Pp. 126-127.
The expression "Bob's your uncle" may have originated from an instance of neptism among British elites: Robert Arthur Talbot Gascoyne-Cecil, 3rd Marquess of Salisbury promoted his nephew, Arthur Balfour, to be Chief Secretary for Ireland.
