Emperor and baronet ordered to carry a piano (9)
I believe the answer is:
bonaparte
'emperor' is the definition.
(Napoleon Bonaparte)
'baronet ordered to carry a piano' is the wordplay.
'ordered' indicates anagramming the letters.
'to carry' means one lot of letters goes inside another.
'piano' becomes 'p' (musical abbreviation).
'baronet' with letters rearranged gives 'bonarte'.
'a'+'p'='ap'
'bonarte' enclosing 'ap' is 'BONAPARTE'.
'and' is the link.
(Other definitions for bonaparte that I've seen before include "Napoleon's surname" , "French military leader" , "French costume drama may involve me" , "Corsican family" , "Exiled emperor" .)
