A record backed by a new nation (6)
I believe the answer is:
angola
'nation' is the definition.
(Angola is an example)
'a record backed by a new' is the wordplay.
'record' becomes 'log' (logging is a kind of recording).
'backed' shows that the letters should be reversed in order.
'by' is a charade indicator (letters next to each other).
'a new' becomes 'an' (I've seen this in other clues**).
'a'+'log'='alog'
'alog' reversed gives 'gola'.
'gola' after 'an' is 'ANGOLA'.
(Other definitions for angola that I've seen before include "Luanda is its capital city" , "West African country" , "Republic of SW Africa" , "Country of SW Africa" , "Country of south-western Africa" .)
