University staff referring to publicity at Queen’s? (7)
I believe the answer is:
readers
'university staff' is the definition.
(reader is a type of academic)
'referring to publicity at queen's?' is the wordplay.
'referring to' becomes 're'.
'publicity' becomes 'ad' (advert).
'at' is a charade indicator (letters next to each other).
'queen's?' becomes 'ers' (abbreviation for Elizabeth Regina).
're'+'ad'+'ers'='READERS'
(Other definitions for readers that I've seen before include "Senior lecturers" , "Checkers of proofs" , "bookworms" , "Lectors" , "Bookish people" .)
