Legislator spilt no tears (7)
I believe the answer is:
senator
'legislator' is the definition.
(senator is a kind of legislator)
'spilt no tears' is the wordplay.
'spilt' indicates anagramming the letters.
'no'+'tears'='notears'
'notears' is an anagram of 'SENATOR'.
(Other definitions for senator that I've seen before include "Member of a governing body" , "politician going wrong" , "One from uni's governing body" , "Roman legislator" , "Member of government" .)
