On a charge being drunk in Alaskan port (9)
I believe the answer is:
anchorage
'alaskan port' is the definition.
(I've seen this in another clue)
'on a charge being drunk' is the wordplay.
'being drunk' indicates an anagram.
'on'+'a'+'charge'='onacharge'
'onacharge' is an anagram of 'ANCHORAGE'.
'in' is the link.
(Other definitions for anchorage that I've seen before include "American city" , "Place for ship to stay - Alaska city" , "northern outpost" , "Cost of mooring ship" , "Alaska's most populous city" .)
