Newsletter (8)
I believe the answer is:
bulletin
'newsletter' is the definition.
(I have seen 'Regular newsletter ' mean 'bulletin' so perhaps 'newsletter' could also mean 'bulletin')
This is the entire clue.
(Other definitions for bulletin that I've seen before include "Brief report issued to the public" , "Regular report" , "Regular news up-date" , "Blunt lie in offical news statement" , "Official statement for publication" .)
