Notice article about details in programme (6)
I believe the answer is:
agenda
'programme' is the definition.
(agenda is a kind of programme)
'notice article about details' is the wordplay.
'notice' becomes 'ad'.
'article' becomes 'a' (indefinite article).
'about' is an insertion indicator.
'details' becomes 'gen' (I've seen this in other clues).
'ad'+'a'='ada'
'ada' placed around 'gen' is 'AGENDA'.
'in' is the link.
(Other definitions for agenda that I've seen before include "To-do list" , "List of items for discussion at a meeting" , "List of items to be done" , "Plan for meeting" , "Timetable" .)
