Publish charter again? (7)
I believe the answer is:
release
This clue is a double definition.
'publish' is the first definition.
('release' can be a synonym of 'publish')
'charter again' is the second definition.
('lease' can be a synonym for 'charter' so perhaps 'release' is OK for 'charter again')
(Other definitions for release that I've seen before include "Free from confinement" , "New film" , "Liberate" , "Set free - publish" , "Free - delivery" .)
