Detroit pizzas and bras: what M&S has got right

LINEN M&S’s range is hugely popular with male and female shoppers, with products including linen shorts, dresses and suits.

UNDERWEAR The retailer is the top seller of bras in the UK and a longrunning collaboration with lingerie model Rosie Huntington-Whiteley has been a hit. SCHOOL UNIFORMS It has long dominated the school uniform market, and sells everything from PE kits to gingham summer dresses. PIZZAS Its Detroit-inspired rectangular pizzas, costing £6, with hog roast and Philly steak toppings, are popular with big families.

BURGERS The ‘best-ever burger’ costs £14 for a pack of eight, contains a ‘hint’ of bone marrow and took a year to develop.
