Journalists in Dorset I fancy (7)
I believe the answer is:
editors
'journalists' is the definition.
(an editor is a senior journalist)
'dorset i fancy' is the wordplay.
'fancy' is an anagram indicator.
'dorset'+'i'='dorseti'
'dorseti' anagrammed gives 'EDITORS'.
'in' is the link.
(Other definitions for editors that I've seen before include "Press employees" , "Senior journalists" , "Employees on paper" , "Newspaper bosses" , "Newspaper heads" .)
