Opposition point of view supports rent rise (10)
I believe the answer is:
resistance
'opposition' is the definition.
(synonyms)
'point of view supports rent rise' is the wordplay.
'point of view' becomes 'stance' (I've seen this in other clues).
'supports' says to put letters next to each other (bottom letters provide a support for the top ones).
'rent' indicates anagramming the letters (rent can mean torn or damaged).
'rise' anagrammed gives 'resi'.
'stance' after 'resi' is 'RESISTANCE'.
(Other definitions for resistance that I've seen before include "Rebels" , "French fighting group" , "Organised covert opposition to an occupying power" , "Withstanding" , "underground movement" .)
