Carry out, commit (10)
I believe the answer is:
perpetrate
This clue is a double definition.
'carry out' is the first definition.
(I've seen this before)
'commit' is the second definition.

(Other definitions for perpetrate that I've seen before include "Commit (crime)" , "Be responsible for" , "Act" , "perform" , "Carry out, commit" .)
