Order bloke on romantic meeting (7)
I believe the answer is:
mandate
'order' is the definition.
(I know that mandate is a more specific form of the action order)
'bloke on romantic meeting' is the wordplay.
'bloke' becomes 'man' (informal term for a man).
'on' is a charade indicator (letters next to each other).
'romantic meeting' becomes 'date' (eg a dinner date).
'man'+'date'='MANDATE'
(Other definitions for mandate that I've seen before include "Authority to do something" , "Decree" , "Official command; commission" , "Authority for action" , "Authority to act" .)
