Do away with endless, middle-class bolshie rubbish (7)
I believe the answer is:
abolish
'do away with' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for abolish that I've seen before include "Quash" , "Put an end to (something)" , "Put an end to (practice)" , "Scrap" , "Put an end to, formally" .)
