The UK's first Xiaomi store has opened in Westfield London.
(Yes Westfield London is the name of the shopping centre, there is another called Westfield Stratford)
This store appears to have been open for three days, (at the time of writing) but Westfield has only just gotten around to announcing it.
The store is open from 10am-10pm Monday to Saturday, and Sundays 12pm-6pm.
The Xiaomi UK website (https://www.mi.com/uk/) now shows the store as the sole entry to the Authorised Mi Store list.
Westfield sent out a marketing email this morning (they acquired mine through free wifi signup) saying that the Mi store is now open.
