Expected publicity people to include note (3)
I believe the answer is:
par
'expected' is the definition.
(as in 'par for the course')
'publicity people to include note' is the wordplay.
'publicity people' becomes 'PR' (public relations).
'to include' indicates putting letters inside.
'note' becomes 'a' (musical note).
'pr' going around 'a' is 'PAR'.
(Other definitions for par that I've seen before include "Standard score for golfers" , "A number of golfing" , "Face value; equal standing" , "Standard number of strokes for a golf-hole" , "Average or normal score" .)
