Backlash from Establishment after Conservative's demotion (8)
I believe the answer is:
reaction
'backlash' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for reaction that I've seen before include "Into care (anag)" , "effect of drugs?" , "Result of stimulus" , "Answer" , "Feedback" .)
