Transmit radio plays for organiser (13)
I believe the answer is:
administrator
'organiser' is the definition.
(I've seen this before)
'transmit radio plays' is the wordplay.
'plays' is an anagram indicator.
'transmit'+'radio'='transmitradio'
'transmitradio' with letters rearranged gives 'ADMINISTRATOR'.
'for' acts as a link.
(Other definitions for administrator that I've seen before include "Runner" , "Manager, controller" , "Official organiser" , "one controls" , "One managing business affairs" .)
