Prize given to Republican fund manager (9)
I believe the answer is:
treasurer
'fund manager' is the definition.
(a treasurer is in charge of funds)
'prize given to republican' is the wordplay.
I cannot quite see how this works, but
'prize' could be 'treasure' (synonyms) and 'treasure' is found in the answer.
'republican' could be 'r' (abbreviation) and 'r' is present in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
(Other definitions for treasurer that I've seen before include "Financial assets manager" , "One of main officers of a society" , "Society official" , "Financial controller" , "Finance expert" .)
