Bottle up seeing journalists on drink (8)
I believe the answer is:
suppress
'bottle up' is the definition.
('suppress' can be a synonym of 'bottle up')
'journalists on drink' is the wordplay.
'journalists' becomes 'press' (I've seen this before).
'on' means one lot of letters go next to another.
'drink' becomes 'sup' (I've seen this before).
'press' put after 'sup' is 'SUPPRESS'.
'seeing' acts as a link.
(Other definitions for suppress that I've seen before include "'Crush, keep down (8)'" , "Forcibly keep down" , "Stifle or overpower" , "Prevent from being circulated" , "Restrain - crush" .)
