Getty ImagesMarks & Spencer has revealed that the contact details and date of births of some customers has been stolen in the recent cyber attack which continues to disrupt its services.
The High Street giant said the personal information taken also included online order histories, but said the data theft did not include useable payment or card details or any account passwords.
M&S was hit by the cyber attack some three weeks ago and is still struggling to get services back to normal, with online orders still suspended.
The retailer said customers would be prompted to reset passwords for accounts "for extra peace of mind".

"Importantly, there is not evidence that the information has been shared," he added.
