Official report of the proceedings of the British Parliament (7)
I believe the answer is:
hansard
'official report of the proceedings of the british parliament' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for hansard that I've seen before include "House journal" , "Printed record of Westminster debates" , "UK parliamentary record" , "Official report of Parliamentary proceedings" , "Official record of Parliament" .)
