Overcoat is new result (6)
I believe the answer is:
ulster
'overcoat' is the definition.
(ulster is a kind of overcoat)
'new result' is the wordplay.
'new' indicates an anagram.
'result' is an anagram of 'ULSTER'.
'is' acts as a link.
(Other definitions for ulster that I've seen before include "Man's overcoat" , "Historic Irish province; heavy overcoat" , "Northern Ireland (loosely)" , "Six, or nine, counties" , "Cloak for an Irish province" .)
