Artist, politician and worker go unchecked (7)
I believe the answer is:
rampant
'unchecked' is the definition.
(I've seen this before)
'artist politician and worker' is the wordplay.
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'politician' becomes 'MP' (Member of Parliament).
'and' is a charade indicator (letters next to each other).
'worker' becomes 'ant' (worker is a type of ant).
'ra'+'mp'+'ant'='RAMPANT'
'go' acts as a link.
(Other definitions for rampant that I've seen before include "Spreading like wildfire" , "Showing unchecked growth" , "running wild" , "Spreading unchecked" , "Unchecked (and violent?)" .)
