New paper socialist got ready (8)
I believe the answer is:
prepared
'got ready' is the definition.
('prepare' can be a synonym of 'get ready')
'new paper socialist' is the wordplay.
'new' is an anagram indicator.
'socialist' becomes 'red' (socialism is often associated with the colour red).
'paper' with letters rearranged gives 'prepa'.
'prepa'+'red'='PREPARED'
(Other definitions for prepared that I've seen before include "Ready for action" , "edited" , "Made or got ready" , "Waiting" , "All set" .)
