Change of rule abroad (7)
I believe the answer is:
foreign
'abroad' is the definition.
('foreign' can be similar in meaning to 'abroad')
'change of rule' is the wordplay.
'change' is an anagram indicator.
'rule' becomes 'reign' (reign is a kind of rule).
'of' is an anagram of 'fo'.
'fo'+'reign'='FOREIGN'
(Other definitions for foreign that I've seen before include "Peculiar" , "Non-native" , "Extraneous" , "Alien" , "Unfamiliar; from abroad" .)
