Bloke with escort on order (7)
I believe the answer is:
mandate
'order' is the definition.
(I've seen this before)
'bloke with escort' is the wordplay.
'bloke' becomes 'man' (I've seen this in other clues).
'with' means one lot of letters go next to another.
'escort' becomes 'date' ('date' can be a synonym of 'escort').
'man'+'date'='MANDATE'
'on' is the link.
(Other definitions for mandate that I've seen before include "Written authority" , "Official order or commission to do something" , "Official command; commission" , "Legal authorisation" , "Authority to act" .)
