God loves hugging liberals after returning each year (6)
I believe the answer is:
apollo
'god' is the definition.
(Apollo is a Greek god)
'loves hugging liberals after returning each year' is the wordplay.
'loves' becomes 'oo' (love means 0 in tennis).
'hugging' indicates putting letters inside.
'liberals' becomes 'll' (a political abbreviation for liberal written twice).
'after' says to put letters next to each other.
'returning each year' becomes 'ap' (I am not sure about this - if you are sure you should believe this answer much more).
'oo' enclosing 'll' is 'ollo'.
'ollo' after 'ap' is 'APOLLO'.
(Other definitions for apollo that I've seen before include "mission of high-flying Americans?" , "Greek sungod, son of Zeus" , "Greek god; large European butterfly" , "US space flight programme, 1961-72" , "Greek god of the sun (6)" .)
