Comic initially carrying on about the press etc. (8)
I believe the answer is:
comedian
'comic' is the definition.
('comedian' can be a synonym of 'comic')
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for comedian that I've seen before include "Cracker?" , "scream?" , "Demoniac kind of funny man" , "One tells jokes" , "wit" .)
