Islander in secret announcement (6)

I believe the answer is:

cretan

'islander' is the definition.
(someone from Crete)

'in secret announcement' is the wordplay.
'in' indicates a hidden word.
'CRETAN' is hidden in the letters of 'secret announcement'.

(Other definitions for cretan that I've seen before include "One from largest Greek isle" , "One comes from a Mediterranean island" , "Greek islander" , "From Greece" , "Native of Greek island south of mainland (6)" .)

I've seen this clue in The Guardian.
