UK convenience retailer Co-op’s chief digital and technology officer Robert Elsey has resigned, becoming the latest senior executive to leave the group. Elsey, who joined in 2021, led its response to the 2025 cyberattack that disrupted operations and exposed data belonging to 6.5 million members. His departure follows recent exits including CEO Shirine Khoury-Haq, food managing director Matt Hood and chair Debbie White. (Retail Week)
