State there's a holdup at Kew, we hear (6)

I believe the answer is:

kuwait

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

'state' is the definition.
(Kuwait is an example)

I cannot understand how the remainder of the clue works.

(Other definitions for kuwait that I've seen before include "Gulf state" , "Country on Persian gulf coveted by Saddam Hussein" , "Country invaded by Iraq" , "Gulf emirate" , "Gulf War liberated it, 1991" .)

I've seen this clue in the Evening Standard.
