African republic; capital Lilongwe (6)
I believe the answer is:
malawi
I believe this clue is a double definition.
'african republic' is the first definition.
(I know that Malawi is a republic)
'capital lilongwe' is the second definition.
(I know that Lilongwe capital of Malawi)
(Other definitions for malawi that I've seen before include "Former Nyasaland" , "Country W. of Lake Nyasa" , "Central African country" , "Landlocked country of south central Africa" , "African country, capital Lilongwe" .)
