Cheat nick accepting blokes' record (8)
I believe the answer is:
document
'record' is the definition.
(I know that record can be written as document)
'cheat nick accepting blokes'' is the wordplay.
'cheat' becomes 'do'.
'nick' becomes 'cut'.
'accepting' means one lot of letters goes inside another.
'blokes'' becomes 'men' (I've seen this in another clue).
'cut' enclosing 'men' is 'cument'.
'do'+'cument'='DOCUMENT'
(Other definitions for document that I've seen before include "Paper, record" , "Piece of writing, of an official nature perhaps" , "Written record" , "Written statement" , "Official paper" .)
