Permission to cut Charlie out (5)
I believe the answer is:
leave
This clue might be a double definition.
'permission' is the first definition.
(leave is permission or authorisation)
'cut charlie out' is the second definition.
'leave' can be an answer for 'cut' (thesaurus). I am unsure of the 'charlie out' bit.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for leave that I've seen before include "Depart - on office holidays?" , "Pull out" , "Exit" , "Brexit's aim" , "Time off, depart" .)
