Party ignores leader of the opposition from clip lacking sensitivity in the plant (8)
I believe the answer is:
laburnum
'sensitivity in the plant' is the definition.
The answer and definition can be both plants as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'party ignores leader of the opposition from clip lacking' is the wordplay.
I cannot quite see how this works, but
'party' could be 'lab' (abbreviation for Labour) and 'lab' is located in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for laburnum that I've seen before include "Source of poison" , "Ornamental tree with hanging clusters of yellow flowers" , "Tree or shrub with bright yellow flowers" , "Album run for the yellow tree" , "Plant with hanging clusters of bright yellow flowers" .)
