Welfare payment, including Channel Islands, easy to manage (6)
I believe the answer is:
docile
'easy to manage' is the definition.
(I've seen this before)
'welfare payment including channel islands' is the wordplay.
'welfare payment' becomes 'dole' (informal term for unemployment benefits).
'including' indicates putting letters inside.
'channel islands' becomes 'ci'.
'dole' enclosing 'ci' is 'DOCILE'.
(Other definitions for docile that I've seen before include "asleep?" , "Willing to obey, not aggressive" , "Gentle and teachable" , "Willing to obey, compliant" , "Easily managed and trainable" .)
