Cultured European newsman (8)
I believe the answer is:
polished
'cultured' is the definition.
('polished' can be a synonym of 'cultured')
'european newsman' is the wordplay.
'european' becomes 'polish' (I've seen this before).
'newsman' becomes 'ed'.
'polish'+'ed'='POLISHED'
(Other definitions for polished that I've seen before include "Shiny; rubbed" , "Made shiny and smooth" , "Genteel - flawless" , "Difference, statistical quantity" , "Shining or refined" .)
