I was in van going north touring hot capital territory (5)
I believe the answer is:
delhi
'capital territory' is the definition.
(National Capital Territory of India)
'i was in van going north touring hot' is the wordplay.
'was in van' becomes 'led' (van can mean the leading part of a group).
'going north' says the letters should be written in reverse.
'touring' is an insertion indicator (touring can mean going round).
'hot' becomes 'h' (abbreviation eg on taps).
'i'+'led'='iled'
'iled' written backwards gives 'deli'.
'deli' enclosing 'h' is 'DELHI'.
(Other definitions for delhi that I've seen before include "Plumbing ring" , "Capital at one time" , "Capital of India" , "Ancient city" , "Indian territory" .)
