UK county Graham represented (6)
I believe the answer is:
armagh
'uk county' is the definition.
'Armagh' can be an answer for 'county' (county of Northern Ireland). I'm not sure about the 'uk' bit.
'graham represented' is the wordplay.
'represented' indicates an anagram.
'graham' with letters rearranged gives 'ARMAGH'.
Can you help me to learn more?
(Other definitions for armagh that I've seen before include "Ulster county" , "Town where all-Ireland bishopric is located" , "County S. of L. Neagh" , "See in Ireland" , "Irish see" .)
