Iceland Supermarket, Overseen by Labour Cost Tsar, Leads UK Rivals in Price Hikes

Iceland, the British grocery chain whose chairman serves as Labour’s cost of living adviser, recorded the fastest price increases among UK supermarkets, according to market data released on June 2, 2026. The findings intensify scrutiny on the government’s affordability agenda and the role of Richard Walker, appointed as the nation’s cost of living tsar in 2025. The data showed Iceland’s prices surged at a pace that left behind rivals including Tesco, Sainsbury’s and Asda, though specific percentage gaps were not immediately detailed. The chain, known for its focus on frozen foods and lower-income shoppers, has hiked costs amid persistent food inflation. Walker’s dual position has drawn criticism from consumer groups, who note the irony of a grocer charging more while advising the government on household financial pressures. The government had not commented by publication time. The development adds to challenges for the Labour administration, already grappling with public discontent over elevated living costs.
