Sainsbury’s has opened the first of 15 stores with budget chain Netto in Leeds, taking the national chain into the £10 billion discount sector for the first time.

The move marks a return to the UK for Netto, which sold its 193 stores to Asda four years ago. The stores will be primarily in the north of England, where Sainsbury’s market share is weaker.

Per Bank, boss of Netto’s owner, Dansk Supermarked, said: “I hope we can set new standards for discounters in the UK. It’s a big risk but I believe we are able to deliver that. We’re a discounter, but a discounter with a Scandinavian twist.”
