Strangely rum end with free vote (10)
I believe the answer is:
referendum
'vote' is the definition.
(I know that referendum is a type of vote)
'strangely rum end with free' is the wordplay.
'strangely' indicates anagramming the letters.
'with' says to put letters next to each other.
'rum'+'end'='rumend'
'rumend' put after 'free' is 'freerumend'.
'freerumend' is an anagram of 'REFERENDUM'.
(Other definitions for referendum that I've seen before include "Plebiscite" , "ballot" , "General vote on a single question" , "General vote on an issue" , "Blame 3 [DAVE] for it" .)
