Marks & Spencer has fully reinstated its Sparks loyalty programme following a damaging cyberattack that disrupted operations earlier this year. The retailer confirmed that online services are back and customers can access offers, discounts, and rewards again.

In April, a cyber breach forced M&S to suspend parts of its IT system and halt Sparks communications. Customers had raised concerns about missing benefits, prompting the company to promise a full recovery of its loyalty platform.

M&S has introduced new Sparks perks to thank users for their patience, including enhanced birthday rewards and complimentary coffees. Staff will also receive a temporary discount boost to 30 percent on selected items this weekend.

Marketing director Sharry Cramond praised staff efforts and customer support during the disruption, calling the recovery a team effort. Meanwhile, according to the UK National Crime Agency, four individuals suspected of involvement in cyber attacks against M&S and other retailers have been released on bail.
