No change in Washington - rarely guilty (6)
I believe the answer is:
nocent
'washington rarely guilty' is the definition.
I can't judge whether this defines the answer.
'no change' is the wordplay.
'change' becomes 'cent' (I have seen 'Small change' mean 'cent' so perhaps 'change' could also mean 'cent').
'no'+'cent'='NOCENT'
'in' is the link.
Can you help me to learn more?
(Other definitions for nocent that I've seen before include "guilty person" , "Harmful" .)
