Lilongwe is its capital (6)
I believe the answer is:
malawi
'lilongwe is its capital' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for malawi that I've seen before include "Country in east central Africa" , "Country formerly known as Nyasaland" , "Central African country" , "Landlocked country of south central Africa" , "A law I'm making up in Southern Africa" .)
