Approve, sanction (6)

I believe the answer is:

ratify

I believe this clue is a double definition.

'approve' is the first definition.
(I've seen this in another clue)

'sanction' is the second definition.
(I've seen this in another clue)

(Other definitions for ratify that I've seen before include "Give formal approval to" , "Authorise" , "Authenticate" , "OK" , "Sign or give formal consent" .)

I've seen this clue in The Sun.
