Subsidised do with no press involved (9)
I believe the answer is:
sponsored
'subsidised' is the definition.
(both can mean supported financially)
'do with no press involved' is the wordplay.
'with' is a charade indicator (letters next to each other).
'involved' indicates anagramming the letters (involved can mean confusing or complex).
'no'+'press'='nopress'
'do' after 'nopress' is 'nopressdo'.
'nopressdo' with letters rearranged gives 'SPONSORED'.
(Other definitions for sponsored that I've seen before include "With backing" , "(Of event) supported financially" .)
