Direct official accompanying the Queen (5)
I believe the answer is:
refer
'direct' is the definition.
(referring is a kind of directing)
'official accompanying the queen' is the wordplay.
'official' becomes 'ref' (match official in football, say).
'accompanying' is a charade indicator (letters next to each other).
'the queen' becomes 'er' (Elizabeth Regina).
'ref'+'er'='REFER'
(Other definitions for refer that I've seen before include "Make an allusion, or send on" , "If special treatment needed, GP might do this" , "Pertain; assign" , "guide" , "Make allusion, direct attention with words" .)
