Leaders of African Cooperation Council raise additional capital (5)
I believe the answer is:
accra
'capital' is the definition.
(capital of Ghana)
'leaders of african cooperation council raise additional' is the wordplay.
'leaders of' suggests taking the first letters.
The initial letters of 'african cooperation council raise additional' is 'ACCRA'.
(Other definitions for accra that I've seen before include "Ghanaian capital" , "West Africa capital" , "foreign capital" , "Ghanaian city" , "African city" .)
