Have Paul sort out the disturbance (8)
I believe the answer is:
upheaval
'the disturbance' is the definition.
(upheaval is a kind of disturbance)
'have paul sort' is the wordplay.
'sort' is an anagram indicator.
'have'+'paul'='havepaul'
'havepaul' with letters rearranged gives 'UPHEAVAL'.
'out' is the link.
(Other definitions for upheaval that I've seen before include "Great disturbance and disorder" , "Disorder, turmoil" , "Violent or sudden change or disruption" , "Violent change or disturbance" , "Turbulence" .)
