Daughter left for Channel port (5)
I believe the answer is:
dover
'channel port' is the definition.
(English Channel port)
'daughter left' is the wordplay.
'daughter' becomes 'd'.
'left' becomes 'over' (I've seen this before).
'd'+'over'='DOVER'
'for' is the link.
(Other definitions for dover that I've seen before include "UK shipping forecast area" , "Channel port" , "The largest English ferry port" , "Roved around the English port" , "Sort of sole" .)
