Panorama may be in favour of religious group seizing power (8)
I believe the answer is:
prospect
'panorama' is the definition.
('prospect' can be a synonym of 'panorama')
'in favour of religious group seizing power' is the wordplay.
'in favour of' becomes 'pro' (I've seen this before).
'religious group' becomes 'sect' (I've seen this before).
'seizing' indicates putting letters inside.
'power' becomes 'p'.
'sect' going around 'p' is 'spect'.
'pro'+'spect'='PROSPECT'
'may be' acts as a link.
(Other definitions for prospect that I've seen before include "Potential customer" , "View - outlook" , "View - chances" , "Extensive landscape" , "Outlook for corps pet" .)
