Political programme to reveal nothing (9)
I believe the answer is:
manifesto
'political programme' is the definition.
'manifesto' can be an answer for 'programme' (I have seen 'electoral programme' mean 'manifesto' so perhaps 'programme' could also mean 'manifesto'). I am not sure about the 'political' bit.
'reveal nothing' is the wordplay.
'reveal' becomes 'manifest' (I've seen this before).
'nothing' becomes 'O' (O resembles 0).
'manifest'+'o'='MANIFESTO'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for manifesto that I've seen before include "statement of policy" , "Statement of policies" , "Written declaration of opinions" , "electoral programme" , "Political statement of intent" .)
