London-based John Lewis opened its first store in 1864. The BRENT CROSS location began trading to the public as part of the mall's March 1976 grand opening. A rebranding -to John Lewis & Partners- was conducted in September 2018. In the mid-2020s, there were thirty-four stores in operation in the United Kingdom.
