Record about holding vote for a leaver? (5)
I believe the answer is:
expat
'a leaver?' is the definition.
(someone who has left their home country)
'record about holding vote' is the wordplay.
'record' becomes 'tape' (taping is a kind of recording).
'about' is a reversal indicator.
'holding' indicates putting letters inside.
'vote' becomes 'x' (how votes are marked).
'tape' back-to-front is 'epat'.
'epat' going around 'x' is 'EXPAT'.
'for' acts as a link.
(Other definitions for expat that I've seen before include "Person living abroad" , "resident abroad" , "overseas settler" , "One living in foreign country" , "one settled abroad" .)
