Westminster-based Marks & Spencer (a.k.a. "M & S") opened a "mini-major" (junior anchor) store at BRENT CROSS CENTRE at the same time that the 2 anchor stores were dedicated. The chain came into being in Leeds in 1884 and currently has over 900 department store and grocery branches in operation in the United Kingdom. There are also M & S stores in over 40 nations around the globe.
