Country north of Namibia (6)
I believe the answer is:
angola
'country north of namibia' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for angola that I've seen before include "SW African country" , "It's no gala in this African country" , "Country of south-western Africa" , "Republic of SW Africa" , "South-west African country, capital Luanda" .)
