Plot to strike that creates uproar (6)
I believe the answer is:
bedlam
'uproar' is the definition.
(I've seen this before)
'plot to strike' is the wordplay.
'plot' becomes 'bed' (a plot of land).
'to strike' becomes 'lam' (to 'lam' means to hit hard).
'bed'+'lam'='BEDLAM'
'that creates' is the link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for bedlam that I've seen before include "Blamed for 9 across? (8)" , "Noisy confused state" , "Blamed for pandemonium" , "State of extreme confusion and disorder" , "Blamed for confused uproar" .)
