Some activist admiring view (5)

I believe the answer is:

vista

'view' is the definition.
(I know that view can be written as vista)

'some activist admiring' is the wordplay.
'some' indicates the answer is hidden within the clue (some parts of the word are used).
'VISTA' is hidden within 'activist admiring'.

(Other definitions for vista that I've seen before include "Panoramic view" , "Prospect, view" , "Outlook" , "Panoramic scene" , "One gives a long look" .)

I've seen this clue in The Daily Express.
