Country pleb losing lead soon (7)
I believe the answer is:
lebanon
'country' is the definition.
(Lebanon is an example)
'pleb losing lead soon' is the wordplay.
'losing lead' means to remove the first letter.
'soon' becomes 'anon' (synonyms).
'pleb' with its first letter removed is 'leb'.
'leb'+'anon'='LEBANON'
(Other definitions for lebanon that I've seen before include "Its capital is Beirut" , "Middle Eastern region" , "Neighbour of Israel" , "Middle Eastern country" , "Country with cedars" .)
