Earn a new remit (5)
I believe the answer is:
merit
'earn' is the definition.
(I've seen this before)
'a new remit' is the wordplay.
'a new' indicates an anagram.
'remit' anagrammed gives 'MERIT'.
(Other definitions for merit that I've seen before include "of a high order?" , "Good point or quality" , "Deserve, be worthy of" , "Deserve; excellence" , "Deserve or warrant" .)
