Scotland’s representative in on RUC reforms (7)
I believe the answer is:
unicorn
'scotland's representative' is the definition.
'unicorn' can be an answer for 'representative' (I have seen 'Representative of Scotland' mean 'unicorn' so perhaps 'representative' could also mean 'unicorn'). I'm unsure of the 'scotland's' bit.
'in on ruc reforms' is the wordplay.
'reforms' indicates an anagram.
'in'+'on'+'ruc'='inonruc'
'inonruc' with letters rearranged gives 'UNICORN'.
Can you help me to learn more?
(Other definitions for unicorn that I've seen before include "Fabulous animal like horse with horn" , "Mythical white horse with one horn" , "Fabulous creature" , "Lion's traditional adversary" , "Team of three" .)
