Easy to manage party (Channel Islands) meeting the French (6)
I believe the answer is:
docile
'easy to manage' is the definition.
(I've seen this in another clue)
'party channel islands meeting the french' is the wordplay.
'party' becomes 'do' (do can informally mean a party).
'channel islands' becomes 'CI'.
'meeting' is a charade indicator (letters next to each other).
'the french' becomes 'le' ('the' in French).
'do'+'ci'+'le'='DOCILE'
(Other definitions for docile that I've seen before include "asleep?" , "Gentle and teachable" , "easy to manage" , "'Pliant, submissive (6)'" , "Manageable" .)
