We asked more than 2,800 Marks & Spencer food shoppers what they think of its stores – find out how M&S stacks up against other supermarkets.

Marks & Spencer is known for selling high-quality food at a premium. But does it deserve its reputation?

M&S began life as a market stall in Leeds in 1884 and today has more than 800 stores in the UK. 

These range from large M&S stores selling a wide range of clothing and homewares, to smaller Simply Food stores, which primarily sell food. But how does Marks & Spencer compare to other supermarkets on value and quality, among other factors?

Is Marks & Spencer the UK's best supermarket?
