European conclusion being reported (7)
I believe the answer is:
'european' is the definition.
'conclusion being reported' is the wordplay.
'conclusion' becomes 'finish' (finish is a kind of conclusion).
'being reported' shows a homophone (sound like).
'finish' sounds like 'FINNISH'.
(Other definitions for finnish that I've seen before include "Nationality of citizens of Helsinki" , "European language" , "foreign language" , "Eg, native to Helsinki" , "race" .)
