A vote on love deity (6)
I believe the answer is:
apollo
'deity' is the definition.
(Apollo is an example)
'a vote on love' is the wordplay.
'vote' becomes 'poll' (polling is a kind of voting).
'on' is a charade indicator (letters next to each other).
'love' becomes 'o' (love means zero in tennis).
'a'+'poll'+'o'='APOLLO'
(Other definitions for apollo that I've seen before include "US moon landing programme" , "Greek god of the sun (6)" , "Greek god; large European butterfly" , "Japanese dish" , "London theatre" .)
