Talk and smooch freely, when abandoning a city (9)

I believe the answer is:

stockholm

'city' is the definition.
(Stockholm is an example)

I don't understand the rest of the clue.

(Other definitions for stockholm that I've seen before include "Sweden's capital city" , "Capital of Sweden" , "Scandinavian capital" , "Swedish city" .)

I've seen this clue in The Guardian.
