text: According to http://osm.mapki.com/history/node.php?id=27365306 , Westminster has spent most of its time as a town rather than a city (especially when it has last been added by locals).
  
  Currently it's a "city" - is that correct?
  
  (the confusing thing here is that "city" in OSM terms means "calls itself a city in real life" - see http://wiki.openstreetmap.org/wiki/Tag:place%3Dcity for the discussion about that)
