Back no EU changes with grace (9)
I believe the answer is:
encourage
'back' is the definition.
(thesaurus)
'no eu changes with grace' is the wordplay.
'changes with' indicates anagramming the letters.
'no'+'eu'='noeu'
'noeu' with its letters mixed up with 'grace' can make 'ENCOURAGE'.
(Other definitions for encourage that I've seen before include "Recommend" , "Hearten, inspire" , "Spurs on" , "Spur on, inspire" , "Motivate" .)
