Pap Leo touring city (6)
I believe the answer is:
aleppo
'city' is the definition.
(Aleppo is an example)
'pap leo touring' is the wordplay.
'touring' indicates an anagram (touring can mean moving around).
'pap'+'leo'='papleo'
'papleo' is an anagram of 'ALEPPO'.
(Other definitions for aleppo that I've seen before include "Ancient city, in Syria" , "Middle East city" , "Lap Poe around the Syrian city" , "City in Syria - lop ape (anag)" , "Foreign city" .)
