Founded by William Morrison in 1899, Wm Morrison Supermarkets is the U.K.'s fourth-largest grocery chain, with a market share of around 10%. The 2004 takeover of rival Safeway transformed the firm in terms of scale and gave it a significant presence outside its base in Northern England. The company operates around 500 stores totalling 1.3 million square meters, entirely in the U.K. The Morrison family still owns around a 10% stake but is no longer otherwise involved in the business. Morrisons has an online presence via a partnership with Ocado and has lately been trying to expand its wholesale channel with new agreements (Amazon, McColl's).
