Part of agenda in a blasted backward country (7)
I believe the answer is:
albania
'country' is the definition.
(Albania is an example)
'part of agenda in a blasted backward' is the wordplay.
'part of' indicates the answer is hidden within the clue.
'backward' is a reversal indicator.
'ainabla' is hidden in the letters of 'agenda in a blasted'.
'ainabla' reversed gives 'ALBANIA'.
(Other definitions for albania that I've seen before include "One country" , "SE European country" , "Balkan country" , "Southeast European republic" , "Tirana is the capital city" .)
