Awkward to be left on the other side of the Channel (6)
I believe the answer is:
gauche
I believe this clue is a double definition.
'awkward' is the first definition.
(I've seen this before)
'left on the other side of the channel' is the second definition.
('gauche' is 'left' in French)
'to be' is the link.
(Other definitions for gauche that I've seen before include "Clumsily tactless" , "Ill-at-ease, awkward in social situations" , "Tactless - blundering" , "Socially awkward or tactless" , "Raw and naive" .)
