Tesco has emerged as a supermarket Christmas winner, growing its UK like-for-like sales by 8.1 per cent over the festive period.

Ken Murphy, Tesco’s chief executive, said the retailer’s focus on looking after customers, including “delivering record availability, robust safety measures and great value” enabled Tesco to maintain strong momentum through the Christmas period, outperforming the market every week.

“We delivered a record Christmas across all of our formats and channels,” he said in a statement. “In response to unprecedented demand for online groceries, colleagues delivered over seven million orders containing more than 400 million individual items over the Christmas period.

In its 19-week third quarter and Christmas trading update, Tesco reported that UK sales grew across all formats, channels and categories.

The retailer said its strong UK sales performance was sustained into the third quarter with like-for-like growth of +6.7 per cent, accelerating to +8.1 per cent at Christmas following improved customer metrics across all areas.

Online sales growth was particularly marked at over +80 per cent, which equates to nearly £1 billion extra sales over the 19-week period, Tesco said
