Ringmaster in Ealing? (3)
I believe the answer is:
ali
'ringmaster' is the definition.
(I've seen this before)
'in ealing?' is the wordplay.
'in' indicates a hidden word.
'ALI' is hidden within 'ealing'.
(Other definitions for ali that I've seen before include "A champ'" , "Egyptian name" , "Champion of ring" , "Muhammad - - , legendary boxer" , "Son-in-law to Muhammad" .)
