Licence given for each delegation (10)
I believe the answer is:
permission
'licence' is the definition.
(thesaurus)
'for each delegation' is the wordplay.
'for each' becomes 'per' (I've seen this before).
'delegation' becomes 'mission' ('mission' can be a synonym of 'delegation').
'per'+'mission'='PERMISSION'
'given' is the link.
(Other definitions for permission that I've seen before include "Visa, eg" , "Allowance" , "Consent, authorisation" , "Leave" , "Green light" .)
