Angling to be outside Centrelink when closing (9)
I believe the answer is:
finishing
'closing' is the definition.
(I know that finishing is a type of closing)
'angling to be outside centrelink' is the wordplay.
'angling' becomes 'fishing' ('fish' can be a synonym of 'angle').
'to be outside' indicates putting letters inside.
'centrelink' becomes 'in' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'fishing' enclosing 'in' is 'FINISHING'.
'when' is the link.
Can you help me to learn more?
(Another definition for finishing that I've seen is " Ending".)
