Labour MP Bell Ribeiro clashed with former Sainsbury’s CEO Justin King over supermarket profits. The pair appeared on ITV’s Peston show on Wednesday to discuss UK supermarkets. Ms Ribeiro said: “I heard earlier supermarkets are profitable because they provide good service, that is not right. Supermarkets are profitable because they sell food and essentials and we need said food and essentials.” Mr King replied: “We are going to disagree completely on that. I profoundly believe that the profit motive is the best way to run a business. “The world comes to the UK to look at our supermarkets.”
