Revolutionary part of download negated programme (6)
I believe the answer is:
agenda
'programme' is the definition.
(agenda is a kind of programme)
'revolutionary part of download negated' is the wordplay.
'revolutionary' shows that the letters should be reversed in order (letters revolve around).
'part of' indicates a hidden word.
'adnega' is hidden in the letters of 'download negated'.
'adnega' written backwards gives 'AGENDA'.
(Other definitions for agenda that I've seen before include "List of items to be done" , "things to discuss" , "Table of business" , "List of items for committee to consider" , "List of matters to be discussed at a meeting" .)
