Passion leading to hot dispute in airport (8)
I believe the answer is:
heathrow
'airport' is the definition.
(London airport)
'passion leading to hot dispute' is the wordplay.
'passion' becomes 'heat' (synonyms).
'leading to' is a charade indicator (letters next to each other) (some letters go before or lead others).
'hot' becomes 'h' (abbreviation eg on taps).
'dispute' becomes 'row' (row is a kind of dispute).
'heat'+'h'+'row'='HEATHROW'
'in' acts as a link.
(Other definitions for heathrow that I've seen before include "lots of movement through the air here" , "London's main airport" , "our counterpart of Charles de Gaulle" , "London airport" , "site for airport" .)
