Managed company with pure naked malice (7)
I believe the answer is:
rancour
'malice' is the definition.
(I've seen this before)
'managed company with pure naked' is the wordplay.
'managed' becomes 'ran' (both can mean organised or was in charge of).
'company' becomes 'co' (abbreviation).
'with' is a charade indicator (letters next to each other).
'naked' says to take the centre (outside letters removed so centre is unclothed).
The middle letters of 'pure' are 'ur'.
'ran'+'co'+'ur'='RANCOUR'
(Other definitions for rancour that I've seen before include "Long-lasting bitterness" , "Bitter resentment" , "generating ill-feeling ..." , "Spiteful ill-feeling" , "Bitter feeling or ill-will" .)
