Papers initially banned under ministerial framework (4)
I believe the answer is:
bumf
'papers' is the definition.
(bumf means printed material)
'initially banned under ministerial framework' is the wordplay.
'initially' suggests taking the first letters.
The first letters of 'banned under ministerial framework' is 'BUMF'.
(Other definitions for bumf that I've seen before include "Boring documents etc" , "Official documents" , "Printed material" , "pile of leaves" , "official papers?" .)
