Provocative article in communist paper? (3,3)
I believe the answer is:
red rag
'provocative article' is the definition.
The definition suggests a singular noun which matches the answer.
'communist paper?' is the wordplay.
'communist' becomes 'red' (red can informally mean communist).
'paper?' becomes 'rag' (rag can mean a newspaper).
'red'+'rag'='RED RAG'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for red rag that I've seen before include "Bull incitor?" , "Something proverbially annoying a bull" , "Provocation to bull" , "might attract a charge" , "It is offensive to a bull" .)
