If established name begins to get into Communist policies? (9)
I believe the answer is:
manifesto
'policies?' is the definition.
(I've seen this before)
'if established name begins to get into communist' is the wordplay.
'established' becomes 'est' (abbreviation).
'name' becomes 'n' (common abbreviation e.g. on forms).
'begins' means one lot of letters go next to another.
'to get into' indicates putting letters inside.
'communist' becomes 'mao' (Mao is an example).
'if'+'est'='ifest'
'ifest' after 'n' is 'nifest'.
'nifest' put within 'mao' is 'MANIFESTO'.
(Other definitions for manifesto that I've seen before include "Written declaration of opinions" , "Soften aim (anag) - platform" , "See 6" , "Declaration of political programme" , "Planks assembled here" .)
