Princess inside in a country (5)
I believe the answer is:
india
'country' is the definition.
(I know that India is a Asian country)
'princess inside in a' is the wordplay.
'princess' becomes 'di' (Princess Diana).
'inside' indicates putting letters inside.
'in'+'a'='ina'
'di' put inside 'ina' is 'INDIA'.
(Other definitions for india that I've seen before include "Gandhi's country" , "I identified on radio" , "Second-most populous country" , "Place of Kipling's birth" , "Republic in south Asia" .)
