He gives editor the victory (5)
I believe the answer is:
edwin
'he' is the definition.
(I've seen this before)
'editor the victory' is the wordplay.
'editor' becomes 'ed' (abbreviation).
'the victory' becomes 'win' (a win is a victory).
'ed'+'win'='EDWIN'
'gives' is the link.
(Other definitions for edwin that I've seen before include "Sir - Landseer, artist" , "old king" , "Old king's" , "Man" , "and 21 Across: Dickens character" .)
