Let pass (6)

Ross

I believe the answer is:

permit

I believe this clue is a double definition.

'let' is the first definition.
('permit' can be a synonym of 'let')

'pass' is the second definition.
(thesaurus)

(Other definitions for permit that I've seen before include "Allow, authorise" , "Licence -- license" , "Let; enabling document" , "Let - pass" , "Warrant" .)

I've seen this clue in The Guardian, the Newsday, The Telegraph and The Globe and Mail.
