Reported European election (4)
I believe the answer is:
poll
'election' is the definition.
(I've seen this before)
'reported european' is the wordplay.
'reported' indicates a 'sounds like' (homophone) clue.
'european' becomes 'Pole' (someone from Poland).
'pole' is a homophone of 'POLL'.
(Other definitions for poll that I've seen before include "Canvass (for opinion); lop (tree)" , "Head; register of voters" , "Record of voting" , "Votes cast at an election" , "Voting process; parrot" .)
