Mother holds back correspondence from the House of Reps (10)
I believe the answer is:
parliament
'the house of reps' is the definition.
I can't tell whether this defines the answer.
'mother holds back correspondence' is the wordplay.
'mother' becomes 'parent' (I've seen this in other clues).
'holds' indicates putting letters inside.
'back' says the letters should be written in reverse.
'correspondence' becomes 'mail' (mail is written correspondence).
'mail' back-to-front is 'liam'.
'parent' going around 'liam' is 'PARLIAMENT'.
'from' is the link.
Can you help me to learn more?
(Other definitions for parliament that I've seen before include "Houses" , "Diet" , "UK legislature" , "Legislative body" , "The law is laid down here" .)
