UK lawmakers question Lloyds over account glitch that exposed customers' details

<p>LONDON, March 17 (Reuters) - Britain's cross-party Treasury Committee has requested further explanation from Lloyds ‌Banking Group over the causes of a ‌glitch on March 12 that let some customers see other ​users' transactions on the bank's digital channels.</p>
<p>"On the face of it, this is an alarming breach of data confidentiality," committee chair Meg Hillier wrote to ‌Lloyds CEO Charlie ⁠Nunn in a letter dated March 17.</p>
<p>Lloyds said at the time that it ⁠was investigating the causes and had swiftly resolved the issue.</p>
<p>Hillier asked Lloyds to provide details including ​the nature ​of the glitch, ​a timeline of its ‌response, what personal information was inadvertently disclosed, and how it may compensate affected customers.</p>
<p>The incident comes amid wider scrutiny of the robustness of banks' digital channels such as apps and websites, as ‌lenders in Britain slash their ​physical branch networks to cut ​costs and shift ​customers online.</p>
<p>The Treasury Committee last year ‌said that nine top ​UK banks and ​building societies had suffered at least 803 hours of unplanned technology and systems outages ​between January 2023 ‌and February 2025, blocking millions of customers ​from accessing their cash.</p>
