Moon race affected Gulf of Guinea republic (8)
I believe the answer is:
cameroon
'republic' is the definition.
(I know that Cameroon is a republic)
'moon race affected' is the wordplay.
'affected' is an anagram indicator.
'moon'+'race'='moonrace'
'moonrace' anagrammed gives 'CAMEROON'.
'gulf of guinea' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for cameroon that I've seen before include "Commonwealth country" , "African country, capital Yaounde" , "Country bordering Nigeria" , "O no, cream turns in Africa" , "Moore can be found out west in Africa" .)
