Mentions a change of names (9)
I believe the answer is:
nominates
'names' is the definition.
(I know this)
'mentions a change' is the wordplay.
'change' indicates an anagram.
'mentions'+'a'='mentionsa'
'mentionsa' with letters rearranged gives 'NOMINATES'.
'of' acts as a link.
(Other definitions for nominates that I've seen before include "Proposes" , "Puts name forward in Minnesota" , "Suggests" , "Propose for election" .)
