Tony winner Vereen (3)
I believe the answer is:
ben
'tony winner vereen' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ben that I've seen before include "Big . . . is a famous London clock-tower" , "A Big London clock tower" , "Second part of 11" , "He's big in London" , "Mountain; man's name" .)
