What one is allowed to eat in foreign parliament? (4)
I believe the answer is:
diet
I believe this is a double definition.
'what one is allowed to eat' is the first definition.
(food making up a person's diet)
'foreign parliament?' is the second definition.
(term for the Japanese parliament)
'in' is the link.
(Other definitions for diet that I've seen before include "See 19" , "Choice of food" , "Legislative assembly in some countries" , "Attempt to shift a few pounds" , "Restricted cheer" .)
