Wailers not beginning to reform country (6)
I believe the answer is:
israel
'country' is the definition.
(Israel is an example)
'wailers not beginning to reform' is the wordplay.
'not beginning' means to remove the first letter.
'to reform' indicates anagramming the letters (letters in a new form).
'wailers' with its initial letter taken away is 'ailers'.
'ailers' is an anagram of 'ISRAEL'.
(Other definitions for israel that I've seen before include "Strange serial country" , "Middle Eastern state" , "Serial about Jewish nation" , "Ale, sir, can be found in the country" , "Eastern Med nation" .)
