The Co-operative Group has completed a clearout of Somerfield's own-label range as it presses on with its programme to erase the retailer's name from the high street completely by next spring.

All own-label lines in the remaining Somerfield stores will now carry their new owner's moniker, 18 months after the chain was acquired by the society in a £1.6bn deal.

It means that Somerfield shoppers will for the first time be able to buy all of The Co-op's 3,000-plus own-label products, while a 'best of the best' programme meant some best-selling Somerfield lines, such as the Simply Value range, have been retained under the The Co-op's branding.

Branded ranges and ­promotions across all stores had also been harmonised, said Co-op Group CEO Peter Marks.

"This is another major milestone in the Somerfield integration programme, which is on track and progressing well," he said. "Our 'best of the best' approach means The Co-operative's own-brand range is now stronger than ever, offering all our customers convenient, quality food without compromise."

In July, The Co-op had a clearout of Somerfield products, with a minimum 50% reduction on every item.
