No longer pending? Right, get busy! (7)
I believe the answer is:
officer
'busy' is the definition.
(busy can informally mean a police officer)
I can't explain the remainder of the clue.
(Other definitions for officer that I've seen before include "'An ... and a Gentleman, film (7)'" , "Possibly a major" , "eg Colonel" , "Commissioned member of armed forces" , "Major, say" .)
