Ambassador fashioned links with one city (8)
I believe the answer is:
helsinki
'city' is the definition.
(Helsinki is an example)
'ambassador fashioned links with one' is the wordplay.
'ambassador' becomes 'he' (His or Her Excellency).
'fashioned' is an anagram indicator.
'with' means one lot of letters goes inside another.
'one' becomes 'i' (Roman numeral).
'links' is an anagram of 'lsnki'.
'lsnki' placed around 'i' is 'lsinki'.
'he'+'lsinki'='HELSINKI'
(Other definitions for helsinki that I've seen before include "Sikh line (anag)" , "Finland's capital" , "1952 Olympic Games venue" , "Liken his strange city to one in Finland" , "Nordic capital" .)
