Marks & Spencer’s profits have plunged as the full impact of the widely-reportedly cyber attack that it suffered earlier in the year has been revealed.

The company reported underlying profits of £184.1 million for the six months to the 27th September, less than half the £413.1m earned in the same period last year.

The disruption, which forced the retailer to suspend online clothing and homeware sales for more than six weeks, hit its non-food operations particularly hard, leaving the clothing and homeware division struggling to recover.
