Morrisons and Iceland Foods have raised concerns that Aldi and Lidl are undermining competition in the UK grocery market by exploiting outdated regulations regarding land acquisition. The Controlled Land Order, established in 2010, prevents larger supermarkets from imposing restrictions on land that would inhibit competitors from opening nearby. However, Aldi and Lidl, the fourth and fifth largest grocery retailers in the UK respectively, are not bound by these rules. Richard Walker, executive chairman of Iceland Foods, stated that the same regulations should apply to all retailers with similar market power to ensure fair competition, especially as household budgets are under pressure. The Competition and Markets Authority (CMA) is currently reviewing these rules to determine if they need to be updated to reflect today's market conditions. Morrisons has also voiced support for extending the Controlled Land Order to include Aldi and Lidl, advocating for a level playing field in the grocery sector.
