Chap tours hot Belgian city (5)
I believe the answer is:
ghent
'belgian city' is the definition.
(I've seen this before)
'chap tours hot' is the wordplay.
'chap' becomes 'gent' (I've seen this in other clues**).
'tours' means one lot of letters goes inside another.
'hot' becomes 'h'.
'gent' placed around 'h' is 'GHENT'.
(Other definitions for ghent that I've seen before include "NW Belgian city" , "City of northwest Belgium, known for its cloth industry" , "Belgian port" , "Flanders city/port" , "Belgian city (from which the "good news" was brought to Aix)" .)
