Mister in Madrid (5)
I believe the answer is:
senor
'mister in madrid' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for senor that I've seen before include "Spanish chap" , "Spanish title" , "Man in Havana ?" , "Snore like Spanish man" , "Title of a Spanish-speaking man" .)
