Uncalled-for (8)
I believe the answer is:
needless
'uncalled-for' is the definition.
(I know that uncalled-for can be written as needless)
This is the entire clue.
(Other definitions for needless that I've seen before include "Superfluous" , "Unwanted" , "Uncalled-for" , "Otiose" , "for no good reason" .)
