Counselling a Democrat on wickedness (6)
I believe the answer is:
advice
'counselling' is the definition.
(I've seen this before)
'a democrat on wickedness' is the wordplay.
'democrat' becomes 'd'.
'on' means one lot of letters go next to another.
'wickedness' becomes 'vice' (I've seen this in another clue).
'a'+'d'+'vice'='ADVICE'
(Other definitions for advice that I've seen before include "Intelligence" , "Supposedly wise words" , "Proposal for an appropriate course of action" , "Recommendation for a course of action" , "Warning - guidance" .)
