Gets hold of Government's original files (6)
I believe the answer is:
grasps
'gets hold of' is the definition.
(I've seen this before)
'government's original files' is the wordplay.
'original' says to take the initial letters (the origin of the word).
'files' becomes 'rasps' (rasp is a kind of file).
The initial letter of 'governments' is 'g'.
'g'+'rasps'='GRASPS'
(Other definitions for grasps that I've seen before include "Takes firm grip of" , "holds" , "Clutches" , "Grips" , "Understands" .)
