Angel making singer turn British (6)
I believe the answer is:
cherub
'angel' is the definition.
(I know that cherub is a type of angel)
'singer turn british' is the wordplay.
'singer' becomes 'cher' (Cher is a US musician).
'turn' becomes 'u' (a 'U-turn' is a kind of turn).
'british' becomes 'b' (abbreviation e.g. in 'BBC').
'cher'+'u'+'b'='CHERUB'
'making' is the link.
(Other definitions for cherub that I've seen before include "Lovely child" , "A heavenly baby" , "Innocent youngster" , "Baby angel" , "Angelic child" .)
