Maseru's country (7)
I believe the answer is:
lesotho
'maseru's country' 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 "Kingdom within South Africa" , "Landlocked country in southern Africa" , "Maseru is this Kingdom's capital" , "Kingdom surrounded by South Africa" , "Kingdom that was formerly Basutoland" .)
