Laity troubled in Catholic country (5)
I believe the answer is:
italy
'catholic country' is the definition.
(I've seen this before)
'laity troubled' is the wordplay.
'troubled' is an anagram indicator.
'laity' anagrammed gives 'ITALY'.
'in' is the link.
(Other definitions for italy that I've seen before include "Land for strange laity" , "Mediterranean nation" , "Laity (anag.)" , "Catholic country" , "It was the core of the Roman Empire" .)
