Coastal resort that has some edge in India (6)
I believe the answer is:
rimini
'coastal resort' is the definition.
(Rimini is a coastal resort in Italy)
'some edge in india' is the wordplay.
'some edge' becomes 'rim' (rim is a kind of edge).
'india' becomes 'i' (phonetic alphabet: alpha, bravo, charlie etc.).
'rim'+'in'+'i'='RIMINI'
'that has' is the link.
(Other definitions for rimini that I've seen before include "Italian coastal city" , "Italian town" , "Italian Adriatic port" , "Francesca's place" , "North-east Italian Adriatic resort" .)
