Panorama is reportedly viewed (5)
I believe the answer is:
scene
'panorama' is the definition.
(I know that panorama can be written as scene)
'reportedly viewed' is the wordplay.
'reportedly' indicates a 'sounds like' (homophone) clue.
'viewed' becomes 'seen' (to view is to see).
'seen' sounds like 'SCENE'.
'is' is the link.
(Other definitions for scene that I've seen before include "Where things happen" , "Landscape; public display of anger" , "Aspect" , "Place of an event - of the crime?" , "Subdivision of a play/film" .)
