One who likes to scorn club first (7)
I believe the answer is:
ironist
'one who likes to scorn' is the definition.
'club first' is the wordplay.
'club' becomes 'iron' (iron is a kind of club).
'first' becomes 'ist'.
'iron'+'ist'='IRONIST'
(Other definitions for ironist that I've seen before include "One using opposites to humorous effect" , "One speaking with hidden meaning" , "Satirical speaker" , "Swift, for one" , "One using a form of satire" .)
