Lord Sugar? (4)

I believe the answer is:
alan
'lord sugar?' is the definition.
(I know that lord sugar given name Alan)
This is all the clue.
(Other definitions for alan that I've seen before include "-- Sugar, British entrepreneur" , "-- Ayckbourn, English dramatist" , "A.A. Milne's first name" , "One of Robin Hood's men was - a Dale" , "English historian/poet" .)
