Urge poor to revolt and interrupt parliament (8)
I believe the answer is:
prorogue
'interrupt parliament' is the definition.
'urge poor to revolt' is the wordplay.
'to revolt' indicates anagramming the letters.
'urge'+'poor'='urgepoor'
'urgepoor' anagrammed gives 'PROROGUE'.
'and' acts as a link.
(Other definitions for prorogue that I've seen before include "Suspend meeting" , "Suspend, postpone" , "Stop meeting" , "Discontinue (a session of parliament)" , "Discontinue meeting" .)
