Bloke getting to see authorisation (7)
I believe the answer is:
mandate
'authorisation' is the definition.
(I've seen this before)
'bloke getting to see' is the wordplay.
'bloke' becomes 'man' (informal term for a man).
'getting to' is a charade indicator (letters next to each other).
'see' becomes 'date' (synonyms).
'man'+'date'='MANDATE'
(Other definitions for mandate that I've seen before include "Make compulsory" , "Legal authorisation" , "approval" , "Decree" , "Authority to do something" .)
