United follower maybe - doing wrong in outskirts of Khartoum? (7)
I believe the answer is:
kingdom
'united follower maybe' is the definition.
I can't tell whether this definition defines the answer.
'doing wrong in outskirts of khartoum?' is the wordplay.
'wrong' indicates an anagram.
'in' is an insertion indicator.
'outskirts of' means to remove the middle letters.
'khartoum' with its middle taken out is 'km'.
'doing' anagrammed gives 'ingdo'.
'ingdo' going within 'km' is 'KINGDOM'.
Can you help me to learn more?
(Other definitions for kingdom that I've seen before include "State ruled by monarch" , "Regal realm" , "Country with royal head of state" , "State with a monarchy" , "Republic? Not so!" .)
