English chap Queen returned to give a new title to (6)
I believe the answer is:
rename
'give a new title to' is the definition.
(I've seen this before)
'english chap queen returned' is the wordplay.
'english' becomes 'e' (abbreviation).
'chap' becomes 'man' (I've seen this before**).
'queen' becomes 'er' (abbreviation for Elizabeth Regina).
'returned' says the letters should be written backwards.
'e'+'man'+'er'='emaner'
'emaner' back-to-front is 'RENAME'.
'to' is the link.
(Other definitions for rename that I've seen before include "Confer new appellation of meaner sort" , "Call again" , "Meaner (anag.)" , "Rechristen" , "Brand again" .)
