Newspaper report dismissing new collection (6)
I believe the answer is:
ragbag
'collection' is the definition.
(ragbag is a kind of collection)
'newspaper report' is the wordplay.
'newspaper' becomes 'rag' (rag is a kind of newspaper).
'report' becomes 'bag' (I can't explain this - if you can you should believe this answer much more).
'rag'+'bag'='RAGBAG'
'dismissing new' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
(Other definitions for ragbag that I've seen before include "Random collection" , "confusion" , "Miscellaneous collection - of fabric scraps?" , "Confused assortment" , "Receptacle for scraps or bits-and-pieces" .)
