Old politician fine after work, retiring (6)
I believe the answer is:
powell
'old politician' is the definition.
(Enoch Powell)
'fine after work retiring' is the wordplay.
'fine' becomes 'well' ('well' can be similar in meaning to 'fine'**).
'after' is a charade indicator (letters next to each other).
'work' becomes 'op' (abbreviation for opus).
'retiring' says the letters should be written in reverse.
'op' written backwards gives 'po'.
'well' put after 'po' is 'POWELL'.
(Other definitions for powell that I've seen before include "Foaming blood he saw" , "controversial politician" , "Enoch -, UK politician" , "Anthony, writer" , "Author of A Dance to the Music of Time, d. 2000" .)
