City rule ok — brief cheer going round (8)
I believe the answer is:
bulawayo
'city' is the definition.
(second largest city in Zimbabwe)
'rule ok brief cheer going round' is the wordplay.
'rule' becomes 'law' (law is a kind of rule).
'ok' becomes 'ay' (archaic alternative to 'yes').
'brief' means to remove the last letter.
'cheer' becomes 'buoy' (buoy can mean to cheer or comfort).
'going round' means one lot of letters goes inside another.
'buoy' with its last letter taken off is 'buo'.
'law'+'ay'='laway'
'laway' inserted into 'buo' is 'BULAWAYO'.
(Other definitions for bulawayo that I've seen before include "Industrial city of Zimbabwe" , "African city" .)
