Prince Charming wants china the French added (7)
I believe the answer is:
charles
'prince' is the definition.
(Prince Charles)
'charming wants china the french added' is the wordplay.
'charming wants china' becomes 'char' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'the french' becomes 'les' (les is the in french).
'added' says to put letters next to each other.
'char'+'les'='CHARLES'
(Other definitions for charles that I've seen before include "King beheaded in 1649" , "[LAWMAKER]?" , "Man's name" , "Possible name" , "- Darwin; - Dickens" .)
