Peace protester and politician allowed in bed together (9)
I believe the answer is:
complicit
'in bed together' is the definition.
(in bed with can mean complicit with)
'peace protester and politician allowed' is the wordplay.
'peace protester' becomes 'co' (abbreviation for conscientious objector).
'and' says to put letters next to each other.
'politician' becomes 'mp' (Member of Parliament).
'allowed' becomes 'licit' (I've seen this before).
'co'+'mp'+'licit'='COMPLICIT'
(Other definitions for complicit that I've seen before include "guilty with others?" , "not without guilt?" , "collaborating" , "Conspiring in illegal activity" , "Unlawfully involved" .)
