Foreigner largely full of hypocritical talk in Spanish city (8)
I believe the answer is:
alicante
'spanish city' is the definition.
(I've seen this before)
'foreigner largely full of hypocritical talk' is the wordplay.
'foreigner' becomes 'alien' ('alien' can be a synonym of 'foreigner').
'largely' means to remove the last letter.
'full of' is an insertion indicator.
'hypocritical talk' becomes 'cant' (I've seen this before).
'alien' with its final letter taken off is 'alie'.
'alie' enclosing 'cant' is 'ALICANTE'.
'in' is the link.
(Other definitions for alicante that I've seen before include "Spanish location" , "foreign port" , "Spanish Mediterranean port" , "European resort" , "Spanish resort" .)
