Tipsy parent drinking whiskey and port (7)
I believe the answer is:
antwerp
'port' is the definition.
(Belgian port)
'tipsy parent drinking whiskey' is the wordplay.
'tipsy' indicates an anagram.
'drinking' means one lot of letters goes inside another (inserted letters are consumed or drunk).
'whiskey' becomes 'W' (phonetic alphabet: alpha, bravo, charlie etc.).
'parent' with letters rearranged gives 'anterp'.
'anterp' enclosing 'w' is 'ANTWERP'.
'and' is the link.
(Other definitions for antwerp that I've seen before include "European city" , "New part of Dutch city" , "Belgian city/port" , "Belgian city port" , "North Belgian port" .)
