A little pouch Anne left in vehicle (7)
I believe the answer is:
channel
'vehicle' is the definition.
(I've seen this before)
'a little pouch anne left' is the wordplay.
'a little' indicates the answer is hidden within the clue (a little bit of the clue).
'CHANNEL' is hidden within 'pouch anne left'.
'in' acts as a link.
(Other definitions for channel that I've seen before include "Means of passage or communication" , "Watercourse and frequency band" , "Medium of transmission" , "Seaway south of England" , "Underground route to France" .)
