Blame leader having quit platform (5)
I believe the answer is:
odium
'blame' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for odium that I've seen before include "Widespread hatred or abhorrence (5)" , "disapprobation" , "Widespread hatred or disgust felt towards person" , "General dislike" , "General hatred or disgust" .)
