Announced toffee-covered fruit possibilities (10)
I believe the answer is:
candidates
'possibilities' is the definition.
(eg possible candidates for a job)
'announced toffee-covered fruit' is the wordplay.
'announced toffee' becomes 'candis' (I can't explain this - if you can you should give a lot more credence to this answer).
'covered' indicates putting letters inside.
'fruit' becomes 'date' (date is a kind of fruit).
'candis' going around 'date' is 'CANDIDATES'.
(Other definitions for candidates that I've seen before include "Entrants" , "those awaiting interview?" .)
