Marks & Spencer was experiencing a strong start to 2025, driven by a fashion revival and warm weather, but this momentum has been disrupted by a significant cyber-attack that halted website sales. In response to the attack, staff have reverted to manual methods such as using pens and paper to manage stock, as internal systems remain down. Additionally, Marks & Spencer has paused the delivery of certain food items to Ocado amid concerns about order statuses and data security.
