Troubled Ulster's outcomes (7)
I believe the answer is:
results
'outcomes' is the definition.
(I know this)
'troubled ulster's' is the wordplay.
'troubled' indicates anagramming the letters.
'ulsters' is an anagram of 'RESULTS'.
(Other definitions for results that I've seen before include "Outcomes, effects" , "Exam marks" , "Outcomes, consequences" , "Outcomes, upshots" , "Outcomes, final scores" .)
