Control freak to switch staff around every now and then (7)
I believe the answer is:
fascist
'control' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for fascist that I've seen before include "on the right wing" , "Right-wing authoritarian" , "Right-wing extremist" , "Authoritarian right-winger" , "Extreme right-winger" .)
