City of low morals to Lima’s north (5)
I believe the answer is:
basel
'city' is the definition.
(Basel is an example)
'low morals to lima's north' is the wordplay.
I cannot really see how this works, but
'low' could be 'base' (synonyms) and 'base' is present in the answer.
'lima' could be 'l' (phonetic alphabet: alpha, bravo, charlie etc.) and 'l' is found in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'of' acts as a link.
Can you help me to learn more?
(Other definitions for basel that I've seen before include "City of Switzerland" , "Swiss city" , "In European city" .)
