Sufficient power to operate choppers (5)

I believe the answer is:

teeth

I believe this clue is a double definition.

'sufficient power to operate' is the first definition.
(eg a public body may be said to have teeth)

'choppers' is the second definition.
(I've seen this before)

(Other definitions for teeth that I've seen before include "Canines, for example" , "Genuine effectiveness" , "Gearwheel cogs" , "Gearwheel projections" , "Effective powers" .)

I've seen this clue in The Guardian.
