Spanish wine and pork pie right for royalist (8)
I believe the answer is:
cavalier
'for royalist' is the definition.
(Cavaliers were royalists in the English Civil War)
'spanish wine and pork pie right' is the wordplay.
'spanish wine' becomes 'cava' (type of wine).
'and' means one lot of letters go next to another.
'pork pie' becomes 'lie' ('pork pie' is Cockney rhyming slang for a lie).
'right' becomes 'r' (common abbreviation).
'cava'+'lie'+'r'='CAVALIER'
(Other definitions for cavalier that I've seen before include "... King Charles, spaniel" , "oblivious to consequences" , "Horseman" , "Haughty" , "High-handed, supercilious" .)
