Complete implement (7)

I believe the answer is:

execute

This clue is a double definition.

'complete' is the first definition.
(I know that execute is a type of complete)

'implement' is the second definition.
(I know that execute is a type of implement)

(Other definitions for execute that I've seen before include "Maybe send to chair" , "Finish off" , "ice" , "Discharge" , "Get it done" .)

I've seen this clue in The Guardian and The Globe and Mail.
