Republican Italy so disposed - to dismiss me? (8)
I believe the answer is:
royalist
'dismiss me?' is the definition.
I can't judge whether this definition defines the answer.
'republican italy so disposed' is the wordplay.
'republican' becomes 'r' (abbreviation).
'disposed' is an anagram indicator.
'italy'+'so'='italyso'
'italyso' with letters rearranged gives 'oyalist'.
'r'+'oyalist'='ROYALIST'
'to' acts as a link.
(Other definitions for royalist that I've seen before include "One pro-monarchy" , "Supporter of monarchy" , "Monarch's supporter" , "Civil War Cavalier" , "one in civil war" .)
