"One Liberal removed from manipulated ballot papers" ( The Sun ?) (7)
I believe the answer is:
tabloid
'one liberal removed from manipulated ballot' is the definition.
I can't tell whether this defines the answer.
'papers the sun ?' is the wordplay.
'papers' becomes 'tab' (tab is a kind of papers).
'the sun ?' becomes 'loid' (I am not sure about this - if you are sure you should believe this answer much more).
'tab'+'loid'='TABLOID'
Can you help me to learn more?
(Other definitions for tabloid that I've seen before include "Star, maybe" , "Populist newspaper" , "Type of newspaper" , "Small-size newspaper" , "Ad lib to get lowbrow newspaper" .)
