Reporter's incapable of producing issue for boss? (5)
I believe the answer is:
baron
'boss?' is the definition.
(eg an oil baron is an oil boss)
'reporter's incapable of producing issue' is the wordplay.
'reporter's' indicates a 'sounds like' (homophone) clue (report can mean to speak something aloud).
'incapable of producing issue' becomes 'barren' (issue can mean one's offspring).
'barren' is a homophone of 'BARON'.
'for' acts as a link.
(Other definitions for baron that I've seen before include "Member of the nobility" , "Noble rank" , "A born nobleman" , "See nobleman" , "Lowest title of peerage" .)
