Range around last items for discussion (6)
I believe the answer is:
agenda
'items for discussion' is the definition.
(I've seen this before)
'range around last' is the wordplay.
'range' becomes 'aga' (I've seen this before).
'around' indicates putting letters inside.
'last' becomes 'end'.
'aga' enclosing 'end' is 'AGENDA'.
(Other definitions for agenda that I've seen before include "Schedule, order of business" , "matters for discussion" , "Item list for meeting" , "Topic list for meeting" , "List of items to be dealt with" .)
