Ruin in Madrid is here (4)
I believe the answer is:
dish
'ruin' is the definition.
(thesaurus)
'in madrid is here' is the wordplay.
'in' indicates a hidden word.
'DISH' is hidden within 'madrid is here'.
(Other definitions for dish that I've seen before include "Lovely" , "bit of pottery?" , "course" , "Container for serving food" , "One who's fetching" .)
