Flushed recording of rules and regulations (3,4)
I believe the answer is:
red tape
'regulations' is the definition.
(I have seen 'Unnecessary regulations' mean 'red tape' so perhaps 'regulations' could also mean 'red tape')
'flushed recording of rules' is the wordplay.
I cannot really see how this works, but
'flushed' could be 'red' (red-faced) and 'red' is found within the answer.
'recording' could be 'tape' (tape recording is a kind of recording) and 'tape' is found in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'and' is the link.
Can you help me to learn more?
(Other definitions for red tape that I've seen before include "legal agreement?" , "Bureaucratic procedures and paperwork" , "officialdom" , "Scarlet ribbon of bureaucracy" , "Petty official procedures" .)
