Squash bottle (7)

I believe the answer is:

repress

I believe this clue is a double definition.

'squash' is the first definition.
(thesaurus)

'bottle' is the second definition.
(thesaurus)

(Other definitions for repress that I've seen before include "Forcibly keep down" , "Put in irons, maybe" , "Silence" , "bottle up" , "Keep in subjection" .)

I've seen this clue in the Evening Standard.
