'Brisbane not capital?': confused European (7)
I believe the answer is:
serbian
'european' is the definition.
(I've seen this before)
'brisbane not capital? confused' is the wordplay.
'not capital?' means to remove the first letter.
'confused' indicates anagramming the letters.
'brisbane' with its first letter taken off is 'risbane'.
'risbane' with letters rearranged gives 'SERBIAN'.
(Other definitions for serbian that I've seen before include "Foreigner" , "Native of Belgrade perhaps" , "Eg, Belgrade native" , "Balkan national" , "European" .)
