Eastern relatives turn up to see victory (4)
I believe the answer is:
nike
'victory' is the definition.
(I've seen this in another clue)
'eastern relatives turn up' is the wordplay.
'eastern' becomes 'e'.
'relatives' becomes 'kin' (I've seen this before).
'turn up' shows that the letters should be reversed in order.
'e'+'kin'='ekin'
'ekin' reversed gives 'NIKE'.
'to see' acts as a link.
(Other definitions for nike that I've seen before include "Victoria" , "Greek goddess, personification of victory" , "bringer of victory" , "Goddess of victory - clothing company" , "Greek winged goddess of victory, and sports goods logo" .)
