This article is poorly researched:
there is a "fourth" Apple Store in the same Westfield shopping centre
as the shuttered Samsung Store.
Yes, the fourth Apple Store out of the three the article's author says there are in London.
Should also add to the list the Kingston, Bromley and Brent Cross stores which are within the Greater London area and maybe even the Reading, Watford and Lakeside stores which lie just outside the Greater London borders.
So seven stores...
