Solitary revolutionary monarchist (8)

I believe the answer is:

royalist

'monarchist' is the definition.
('royalist' can be a synonym of 'monarchist')

'solitary revolutionary' is the wordplay.
'revolutionary' indicates an anagram.
'solitary' is an anagram of 'ROYALIST'.

(Other definitions for royalist that I've seen before include "For queen" , "opponent of Republicans" , "One pro-monarchy" , "Civil War Cavalier" , "rightwinger?" .)

I've seen this clue in The Telegraph.
