Man upset with tunnel cancellation (9)
I believe the answer is:
annulment
'cancellation' is the definition.
(I've seen this before)
'man upset with tunnel' is the wordplay.
'upset with' indicates an anagram.
'man' with its letters mixed up with 'tunnel' makes 'ANNULMENT'.
(Other definitions for annulment that I've seen before include "cancellation" , "Invalidation" , "Countermand" , "dissolution" , "Declaration of invalidity, of a marriage say" .)
