Promotes nation state (10)

I believe the answer is:

queensland

'state' is the definition.
(Queensland is an example)

'promotes nation' is the wordplay.
'promotes' becomes 'queens' (queening is a kind of promoting).
'nation' becomes 'land' ('land' can be a synonym of 'nation').
'queens'+'land'='QUEENSLAND'

(Other definitions for queensland that I've seen before include "Australian state" , "NE state of Australia" , "Australian territory" , "part of Australia" .)

I've seen this clue in The Telegraph.
