St Michael is a brand that was owned and used by Marks and Spencer from 1928. The brand was introduced by Simon Marks in 1928, after his father and co-founder of Marks & Spencer, Michael Spencer. By 1950, virtually all goods were sold under the St Michael brand. In 2000, Marks & Spencer shifted to the Marks & Spencer brand. The St Michael name was subsequently adopted as a ‘quality guarantee’ and appeared as the St Michael Quality Promise on the back of food products, on the side of delivery vehicles and on in-store ordering receipts. 

Slide The company put its main emphasis on quality, including a 1957 stocking size measuring system. For most of its history, it has also had a reputation for offering fair value for money.
