A politician from the nor' east (7)
I believe the answer is:
senator
'a politician' is the definition.
(senator is a kind of politician)
'from the nor' east' is the wordplay.
'from' is an anagram indicator (from the letters).
'nor'+'east'='noreast'
'noreast' with letters rearranged gives 'SENATOR'.
(Other definitions for senator that I've seen before include "Member of upper house of legislature" , "US/Roman politician" , "Member of the Upper House of the US Congress" , "Member of government" , "Statesman -- treason (anag)" .)
