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

'shuts' is the definition.
('close' can be a synonym of 'shut')

I can't explain the rest of the clue.

(Other definitions for closes that I've seen before include "Shuts" , "comes to an end" , "Wind up" .)

I've seen this clue in the Evening Standard.
