No ideas in reforming some islands (9)
I believe the answer is:
indonesia
'some islands' is the definition.
(island nation)
'no ideas in reforming' is the wordplay.
'reforming' is an anagram indicator.
'no'+'ideas'+'in'='noideasin'
'noideasin' anagrammed gives 'INDONESIA'.
(Other definitions for indonesia that I've seen before include "SE Asian country" , "Asian country, capital Jakarta" , "part of Asia" , "Muslim republic" , "somewhere in Asia" .)
