Maestro elected to double back on opera (9)
I believe the answer is:
toscanini
'maestro' is the definition.
(I've seen this before)
'elected to double back on opera' is the wordplay.
'elected' becomes 'in' (in government).
'to double' becomes 'in' (I can't justify this - if you can you should believe this answer much more).
'back' shows that the letters should be reversed in order.
'on' is a charade indicator (letters next to each other).
'opera' becomes 'tosca' (Giacomo Puccini opera).
'in'+'in'='inin'
'inin' reversed gives 'nini'.
'nini' after 'tosca' is 'TOSCANINI'.
Can you help me to learn more?
(Other definitions for toscanini that I've seen before include "Arturo --, Italian conductor" , "Old conductor" , "Maestro" , "Virtuoso conductor" , "He conducted" .)
