Polish administrator putting down resistance (7)

I believe the answer is:

perfect

I'm a little stuck... Click here to teach me more about this clue!

'polish' is the definition.
(I know that polish is a kind of perfect)

I can't explain the remainder of the clue.

(Other definitions for perfect that I've seen before include "Mature" , "Polish" , "Ideal, flawless" , "Getting by scheming" , "Make right" .)

I've seen this clue in The Times.
