Election worker sails south with queen (9)
I believe the answer is:
canvasser
'election worker' is the definition.
'canvasser' can be an answer for 'worker' (canvasser is a kind of worker). I'm not sure about the 'election' bit.
'sails south with queen' is the wordplay.
'sails' becomes 'canvas' (I've seen this before).
'south' becomes 's' (abbreviation).
'with' is a charade indicator (letters next to each other).
'queen' becomes 'ER' (short for Elizabeth Regina ie Queen Elizabeth).
'canvas'+'s'+'er'='CANVASSER'
Can you help me to learn more?
(Other definitions for canvasser that I've seen before include "Seeker of opinions" , "One soliciting votes" , "Electioneer" , "Party worker" , "Petitioner who seeks sales or votes" .)
