African kingdom (7)
I believe the answer is:
lesotho
'african kingdom' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for lesotho that I've seen before include "Country, an enclave of South Africa, capital Maseru" , "Country entirely within South Africa" , "South African kingdom" , "Kingdom that was formerly Basutoland" , "He loots (anag) -- southern African kingdom" .)
