Aspire to reform an old country (6)
I believe the answer is:
persia
'an old country' is the definition.
(historical term for Iran)
'aspire to reform' is the wordplay.
'to reform' is an anagram indicator (letters in a new form).
'aspire' anagrammed gives 'PERSIA'.
(Other definitions for persia that I've seen before include "Old Iran" , "Old land" , "Former name of Iran" , "Iran, formerly" , "Aspire to this old country" .)
