One fleecing his subjects? (7)
I believe the answer is:
shearer
'one fleecing his subjects?' is the definition.
The definition suggests a singular noun which matches the answer.
This is all the clue.
Can you help me to learn more?
(Other definitions for shearer that I've seen before include "Alan - - , Newcastle striker" , "One that's fleeced" , "Man clipping sheep" , "Dancer" , "Sheep barber?" .)
