Foreign nanny nursing European throwback to English queen (4,6)
I believe the answer is:
anne boleyn
'queen' is the definition.
(I've seen this before)
'foreign nanny nursing european throwback to english' is the wordplay.
'foreign' indicates anagramming the letters (foreign order of the letters).
'nursing' is an insertion indicator.
'european throwback' becomes 'bole' (I can't justify this - if you can you should believe this answer much more).
'to' says to put letters next to each other (I've seen this in other clues).
'english' becomes 'e' (abbreviation).
'nanny' anagrammed gives 'annyn'.
'bole' put after 'e' is 'ebole'.
'annyn' going around 'ebole' is 'ANNE BOLEYN'.
(Other definitions for anne boleyn that I've seen before include "person finding a monarch's favour" , "Henry VIII's 2nd wife" , "Henry VIII's second queen" , "Second wife of Henry VIII" , "Mother of Elizabeth I" .)
