New Delhi's nation (5)
I believe the answer is:
india
'new delhi's nation' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for india that I've seen before include "The world's most populous democracy" , "Code for the letter I" , ""Bharat", locally" , "Large subcontinent of Asia" , "One preceding Juliet" .)
