Serial that's diverted a country (6)
I believe the answer is:
israel
'a country' is the definition.
(Israel is an example)
'serial that's diverted' is the wordplay.
'that's diverted' is an anagram indicator (letters must be diverted to different positions).
'serial' is an anagram of 'ISRAEL'.
(Other definitions for israel that I've seen before include "Middle Eastern state" , "Serial set in Middle East state" , "Serial about middle-east state" , "Eastern Med nation" , "Lear is to be found in this state" .)
