Labour wants Turkey to benefit (7)
I believe the answer is:
travail
'labour' is the definition.
(travail is a kind of labour)
'turkey to benefit' is the wordplay.
'turkey' becomes 'tr' (I've seen this in other clues).
'to benefit' becomes 'avail' (I've seen this before).
'tr'+'avail'='TRAVAIL'
'wants' acts as a link.
(Other definitions for travail that I've seen before include "Exertion, elbow grease" , "Painful or laborious effort, like childbirth" , "Painful labour" , "Toil - anguish" , "Labour, toil" .)
