One in 100 (7)
I believe the answer is:
senator
'one in 100' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for senator that I've seen before include "Upper house US Congressman" , "Legislator -- treason (anag)" , "Member of the Second House" , "Roman legislator" , "Member of government" .)
