Wailers not beginning to reform country (6)
I believe the answer is:
israel
'country' is the definition.
(I know that Israel is a country)
'wailers not beginning to reform' is the wordplay.
'not beginning' means to remove the first letter.
'to reform' is an anagram indicator (letters in a new form).
'wailers' with its first 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" .)
