Mean Tory changes for capital (8)
I believe the answer is:
monetary
'capital' is the definition.
(thesaurus)
'mean tory changes' is the wordplay.
'changes' is an anagram indicator.
'mean'+'tory'='meantory'
'meantory' with letters rearranged gives 'MONETARY'.
'for' acts as a link.
(Other definitions for monetary that I've seen before include "involving finances" , "of LSD?" , "Army note (anag) - financial" , "of bread" , "Fiscal" .)
