Doha's nation (5)
I believe the answer is:
qatar
'doha's nation' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for qatar that I've seen before include "Doha's state" , "Sheikhdom due to host the 2022 World Cup" , "State in the Persian Gulf" , "who won the cup in 2010?" , "Arab country" .)
