Role chair played in Belgian city (9)
I believe the answer is:
charleroi
'belgian city' is the definition.
(I've seen this before)
'role chair played' is the wordplay.
'played' indicates an anagram (letters playing around).
'role'+'chair'='rolechair'
'rolechair' anagrammed gives 'CHARLEROI'.
'in' acts as a link.
(Other definitions for charleroi that I've seen before include "Belgian place" , "European location" , "in Belgium" , "Belgian city" , "somewhere near Brussels" .)
