People of the wide open spaces (5)

I believe the answer is:

moors

I believe this is a double definition.

'people' is the first definition.
(Moor is an example)

'the wide open spaces' is the second definition.
(thesaurus)

'of' is the link.

(Other definitions for moors that I've seen before include "Ties up a boat" , "Secures" , "wild places" , "wild areas" , "Conquerors once" .)

I've seen this clue in the Evening Standard.
