Fly vassal becomes head of guild (8)

I believe the answer is:

alderman

(Other definitions for alderman that I've seen before include "Member of a local legislative body" , "Former civic dignitary" , "Old municipal official" , "superior member of county council" , "Bigwig" .)

I've seen this clue in The Times.
