Request daily list for MPs (5,5)
I believe the answer is:
order paper
'list for mps' is the definition.
'request daily' is the wordplay.
'request' becomes 'order' (ordering is a kind of requesting**).
'daily' becomes 'paper' (newspaper).
'order'+'paper'='ORDER-PAPER'
(Other definitions for order paper that I've seen before include "parliamentary agenda" , "Use services of Wernham Hogg" , "where business is down" , "source of parliamentary information?" , "Legislative agenda" .)
