Swiss capital flow in Scotland reported? (5)
I believe the answer is:
berne
'swiss capital' is the definition.
(capital of Switzerland)
'flow in scotland reported?' is the wordplay.
'flow in scotland' becomes 'burn' (Scottish term for a river).
'reported?' indicates a 'sounds like' (homophone) clue.
'burn' is a homophone of 'BERNE'.
(Other definitions for berne that I've seen before include "Swiss capital" , "Capital of Switzerland" , "Swiss city (1886 copyright convention)" .)
