Wm Morrison Supermarkets plc, trading as Morrisons, is the fourth largest chain of supermarkets in the United Kingdom, and is headquartered in Bradford, West Yorkshire, England. Founded in 1899 by William Morrison, hence the abbreviation Wm Morrison, it began as an egg and butter stall in Rawson Market, Bradford, England. Until 2004, Morrisons store locations were primarily focused in the North of England, but with the takeover of Safeway in that year, the company's presence increased significantly in the South of England, Wales and Scotland. As of 2016 the company had 498 superstores across England, Wales and Scotland, as well as one in Gibraltar. As of April 2019, Morrisons employed 110,000 employees, and served around 11 million customers each week. Morrisons' market share in August 2017 was 10.14%, down 0.86% from 2015[8]—behind Tesco (27.8%), Sainsbury's (15.8%) and Asda (15.3%) but ahead of Aldi (7%). The company is listed on the London Stock Exchange and is part of the FTSE 100 Index of companies.
