Parliament's reduced intake (4)
I believe the answer is:
diet
This might be a double definition.
'parliament's' is the first definition.
(thesaurus)
'reduced intake' is the second definition.
'diet' can be an answer for 'intake' (I have seen 'regular intake' mean 'diet' so perhaps 'intake' could also mean 'diet'). I am not sure about the 'reduced' bit.
Can you help me to learn more?
(Other definitions for diet that I've seen before include "Part of regime" , "Attempt to shift a few pounds" , "Worms had one" , "Food and drink regularly consumed" , "Calorie-watching regimen" .)
