Point seen in last agenda (5)
I believe the answer is:
stage
'point' is the definition.
('stage' can be a synonym of 'point')
'in last agenda' is the wordplay.
'in' indicates a hidden word.
'STAGE' can be found hidden inside 'last agenda'.
'seen' is the link.
(Other definitions for stage that I've seen before include "Gates (anag.)" , "Phase - platform" , "Form of transport" , "Rostrum" , "Support for acting" .)
