Votes on free movement - new bill is written up (9)
I believe the answer is:
referenda
'votes' is the definition.
(referendum is a kind of vote)
'free movement new bill is written up' is the wordplay.
'movement' is an anagram indicator.
'new' becomes 'ren' (I can't explain this - if you can you should believe this answer much more).
'bill' becomes 'ad' (advertisement stuck on wall).
'is written up' shows that the letters should be reversed in order.
'ad' backwards is 'da'.
'free' with letters rearranged gives 'refe'.
'refe'+'ren'+'da'='REFERENDA'
'on' acts as a link.
Can you help me to learn more?
(Other definitions for referenda that I've seen before include "General votes" , "submissions to people" , "mass votes" , "decisions for people" , "Votes put to country generally 9)" .)
