Council member (8)
I believe the answer is:
alderman
'council member' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for alderman that I've seen before include "superior member of county council" , "Civic officer" , "In England and Wales, a former senior local councillor" , "Member of English county council" , "Member of an English city council" .)
