Consequences of Ulster's troubles (7)
I believe the answer is:
results
'consequences' is the definition.
(I know this)
'ulster's troubles' is the wordplay.
'troubles' is an anagram indicator (I've seen 'troubled' mean this).
'ulsters' anagrammed gives 'RESULTS'.
'of' is the link.
(Other definitions for results that I've seen before include "Outcomes, effects" , "Outcomes, consequences" , "Outcomes, final scores" , "Exam marks" , "Outcomes, upshots" .)
