Upper class taken in by government figure (6)
I believe the answer is:
statue
'figure' is the definition.
(statue is a kind of figure)
'upper class taken in by government' is the wordplay.
'upper class' becomes 'u' (as in U- and non-U speech).
'taken in by' means one lot of letters goes inside another.
'government' becomes 'state' (the state can mean government authority).
'u' put within 'state' is 'STATUE'.
(Other definitions for statue that I've seen before include "Solid carved or cast image" , "Use tat (anag.)" , "Three-dimensional representation" , "As created by 3dn" , "Sculptured likeness" .)
