Over 200 Boots stores are at risk of closure as the company's owners look to cut costs.
Walgreens Boots Alliance (WBA) said it will be reviewing its stores over the next 12 to 18 months, with a particular focus on areas where there is more than one Boots store.
It said it regularly reviews "underperforming stores and opportunities for consolidation" and admitted it does not have "a major programme envisaged".
In April, WBA said it would take "decisive steps" as part of a "significant restructuring" to reduce its costs. At the time, Walgreens boss Stefano Pessina warned that market challenges had "accelerated" in the three months to the end of February.
