The supermarket giant has vowed to stop its “anti-competitive restrictions” following a probe by the Competition and Markets Authority (CMA) and its own internal investigations.

Tesco said it has reviewed more than 5,300 leases after the CMA first discovered that the grocer had been preventing landlords from letting property to other supermarkets back in 2018.

Following the review, Tesco found a total of 23 breaches, including 20 lease agreements that allowed the retailer “exclusive rights” to sell groceries in certain areas for longer than the five-year period permitted under the Groceries Market Investigation (Controlled Land) Order 2010.
