A number of people run television for a county (8)
I believe the answer is:
somerset
'a county' is the definition.
(I've seen this before)
'a number of people run television' is the wordplay.
'a number of people' becomes 'some' (some people).
'run' becomes 'r' (cricket abbreviation).
'television' becomes 'set' (I've seen this in other clues).
'some'+'r'+'set'='SOMERSET'
'for' acts as a link.
(Other definitions for somerset that I've seen before include "English territory" , "County; acrobat move" , "Cheddar Gorge's county" , "Street location" , "SW county" .)
