Record rise in disorder after parties (7)
I believe the answer is:
dossier
'record' is the definition.
(dossier is a kind of record)
'rise in disorder after parties' is the wordplay.
'in disorder' is an anagram indicator.
'after' means one lot of letters go next to another.
'parties' becomes 'dos' (do is a kind of party).
'rise' anagrammed gives 'sier'.
'sier' put after 'dos' is 'DOSSIER'.
(Other definitions for dossier that I've seen before include "File of papers (sometimes dodgy)" , "File of documents" , "Papers containing detailed information about a particular person" , "brief" , "A collection of papers" .)
