Very keen to request reporting restriction (7,5)
I believe the answer is:
gagging order
'reporting restriction' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'very keen to request' is the wordplay.
'very keen' becomes 'gagging' (I can't explain this - if you can you should believe this answer much more).
'to request' becomes 'order' (an order is a request from someone in authority).
'gagging'+'order'='GAGGING ORDER'
Can you help me to learn more?
(Other definitions for gagging order that I've seen before include "fraternity of comedians?" , "Speech impediment" .)
